3.1 Initialization
Connect the power supply of the ACT-9X and then turn on the exciter via the power switch located on
the rear of the unit. The initialization process takes about 5 seconds to finish while the RF output level
gradually increases to the pre-set value.
The ACT-9X may be configured to operate in Legacy (A/53 8VSB), M/H (A/153), or SFN
(A/110:2011) modes and supports ASI, SMPTE310, and TSoIP input streams. The unit operates upon a TS
signal applied to the TS inputs on the back of the unit and performs a modulation at the specified transmit
frequency. The ACT-9X also has composite video and stereo audio input which can support NTSC and
PAL if analog TV option is installed.
The first step after turning on the unit is to confirm the desired operating frequency. Please see Table 4
below for details.
3.2 Query Mode
Query mode is a mode which displays parameters and status of the exciter. There are four pages in
query mode. Press the "Right" or "Left" button to switch between different pages which are shown in Table
2 through Table 5 below.
Note: The settings shown in the tables below for illustration purposes only and may be different from those
in actual use.

Version 1.4 05/23/2014 Page 10 of 35
Note:
1) The "SNR", "LID" and "UID" in Table 2 are the measurement of feedback signal quality. This
feedback signal could be from the transmitter RF System coupling ports and their range is from -30
dBm to 0 dBm (Recommended range is -15 dBm to -5 dBm). These measurements are derived from
the After-filter Feedback Signal connected to the rear port [RF IN A] BNC connector. If there is no
signal connected, these readings will not be available or not valid. The "SNR" is measured with
equalization on. It takes about 10 seconds to get the first reading of "SNR", and about 3 seconds to get
the first reading of "LID" and "UID". After averaging, the upper limit of the "SNR" display is about
41 dB and the upper limit of the IMD display is about 61 dB.
2) The Exciter has 4 ASI inputs which are divided into "GRP1" and "GRP2". It also has one SMPTE310
input. In “AUTO” mode, the priority between "GRP1", "GRP2" and SMPTE310 is
"GRP1">SMPTE310>"GRP2". "GRP1" consist of [TS_IN_1A] and [TS_IN_1B], the former input
has higher priority than the latter input. And "GRP2" consist of [TS_IN_1C] and [TS_IN_1D], both
inputs have the same priority. Each input has three statuses: "USED", "RDY" and "ERR". For
example, "A_USED" of "GRP1" means input stream connected to [TS_IN_1A] is synced and used. If
at the same time, an input stream is connected to [TS_IN_2B] is synced as well, since "GRP1" has
higher priority than "GRP2" in "AUTO" mode, so "GRP2" status is "B_RDY" which means the input
stream of Group 2 is standby. Refer to Chapter 5 Troubleshooting for more detailed information.
3) The "CTRL" status in Table 4 indicates "RMT" (Remote) mode or "LCA" (Local) mode. When in
"LCA" mode, the exciter can only be controlled by the front panel interface and when in "RMT"
mode, settings from the front panel keyboard are ignored - with the exception of "RMT"/"LCA"
setting - and while in RMT mode, only commands from the remote control interface, such as the
WEB, serial port, or Dry Loop are processed.
4) If the internal GPS receiver is selected as the system time reference, its "GPS" and "1PPS" status are
shown on the third page in query mode with additional details are shown on the fourth page (as shown
in Table 5).
In Table 5, “YY-MM-DD” and “HH-MM-SS” is the current date and time, which are only available or
valid after the internal GPS is locked. "SAT" is the number of satellites acquired by the internal GPS
receiver, and “ANT” is the status of the GPS antenna.
"Status" and "Freq" show the sync-up status of system clock with the internal GPS. "Status" is a Hex
number value from 0x0 to 0xF. A higher number represents better sync and higher frequency stability.
"Freq" is the current frequency accuracy number in the format of ±A×10-B and has ±1×10-7 as original
value.

3.3 User Menu
In Control mode, the user may modify configuration settings of the exciter. There are two levels of
control, the User Menu and the Advanced Menu. To enter the User Menu, press both the "Left" and
"Right" buttons at the same time while in query mode. The User Menu in control mode is shown below in
Table 6. In the next section we will present the Advanced Menu.
Table 6 Main Menu

*SYSTEM RF FREQ NET MODE CONFIG TS
The Main User Menu consists of 6 sub-menus: SYSTEM, RF, FREQ, NET, MODE, CONFIG and
TS.
Once at the main menu, press the "Left" or "Right" buttons to move the cursor and navigate to the
desired sub-menu. Once the cursor is positioned just above the desired sub-menu, press the "OK" button to
enter the target sub-menu. When in the corresponding sub-menu, press "Left" or "Right" button to move
the cursor to the target parameter and then press the "Up" or "Down" buttons to select different options
from the drop-down boxes. Once you have selected the desired option, press the "OK" button to apply
and save, or press the "ESC" button to skip the changes and return to the upper menu.
All the parameters of sub-menus are shown in Tables 7 through Table 14 respectively.

Note:
1) The "CTL" (Control) setting has two options, "RMT" (Remote) and "LCA" (Local). The exciter can
be switched between these two modes only via the front panel interface. When in "Local" mode, the
exciter can only be controlled by the front panel interface and all commands from serial port or WEB
are ignored. When in "Remote" mode, settings from the front panel keyboard are ignored - with the
exception of "RMT"/"LCA" setting, and only commands from the remote control interface, such as
serial port or WEB, are processed. Notice that LED "SysErr" remains on all the time in "LCA" mode,
and only indicates a SysErr when it is flashing.

Version 1.4 05/23/2014 Page 12 of 35
2) If the exciter supports "MH" option, then the "MODE" parameter in "SYSTEM" sub-menu has 2
options available: "Legacy" and "MH". If "Legacy" is selected, the exciter will operate according to
the ATSC (A_53) Legacy standard, otherwise if option "MH" is selected, the exciter will operate in
compliance with the ATSC_MH (A_153) standard.
3) If the exciter supports "SFN" option, then the "NET" parameter in "SYSTEM" sub-menu has 2
options available: "MFN" and "SFN".
4) The "ADPC" parameter in the "SYSTEM" sub-menu has options of "UPDATE", "HOLD" and
"OFF". If option "OFF" is selected, the ADPC function will be turned off (no correction applied). If
option "HOLD" is selected, the exciter will apply the last stored linear and non-linear correction
coefficients. If both feedback signals are connected properly and option "UPDATE" is selected, this
will cause the exciter to run the Adaptive Digital PreCorrection (ADPC) function, automatically
computing coefficients for both the linear and non-linear pre-correction for the entire transmission
system including the distortion of both transmitter and band-pass filter. This process takes about 8 to
10 minutes, after which the computed corrections are automatically stored in nonvolatile memory.
Please refer to Chapter 4 for detailed information.
5) "GRP" and "INPUT" are used together to configure specific input streams. The default settings are
both "AUTO", which allow the exciter to run auto-detection and switchover among all 4 ASI inputs
and 1 SMPTE310 input. Under the default settings, the priority of all 5 inputs is
1A>1B>SMPTE310>1C=1D.
6) The "GPS" parameter in "SYSTEM" sub-menu has options "EXT", "INT" and "AUTO". If option
"EXT" is selected, it will use external 10 MHz and 1PPS signals from port [10M_IN] and Port
[1PPS_IN] as clock reference. If option "INT" is selected, it will use internal GPS receiver as time
reference. Or if option "AUTO" (default) is selected, it will switch between these two options and
external GPS has a higher priority than the internal GPS receiver, which means only when there is no
external GPS connected to the exciter, it will use the internal GPS receiver as time reference. Keep in
mind that the internal GPS receiver would not start properly if an antenna is connected after it's
powered up. So the correct order is to connect the antenna first and then to power up the exciter
afterward.

Note:
1) The RF parameter in the “RF” sub-menu turns the RF output of the exciter ON or OFF.
2) The POWER parameter specifies the RF output power level in dB (in the range of -25 to +5 dBm,
note: typical exciter output level is < or = 0 dBm).
3) The "AGC" parameter in the "RF" sub-menu is used to engage or disengage the exciter system-level
automatic gain control. AGC has options "ON" and "OFF". "LVL" and "REF" are decimal numbers
whose range is from 0 to 255. " LV L" provides a reading of the DC voltage from [AGC IN] or the RF
signal level from [RF_IN_A] which reflects the AGC feedback signal level, and "REF" is the
reference value (or target) of the AGC function. When AGC is turned ON for the first time, the "LVL"
will be saved automatically to "REF" as a reference. So if the AGC feedback signal level changes due
to temperature differences or mismatch impedance, etc., the reading of "LVL" will be different from
that of "REF", and the AGC function starts to slowly adjust the output level of the exciter to approach
to the pre-set reference level. The AGC adjustable range is from +1 dB to -10 dB.

Note:
1) The FREQ parameter in the “FREQ” sub-menu specifies the channel frequency for the modulated RF
output signal of the exciter.
2) The "Hz" parameter provides a direct adjustment (offset) of the frequency of the FREQ RF output
signal. The range is -50,000 Hz to +50,000 Hz, with steps of 1 Hz. This feature is designed for up to
50 kHz spectrum shift as ATSC standard required, or adjustment of the output frequency for carrier

Note:
1) "IP", "GATEWAY", and "MASK" are used to establish a valid Ethernet connection for remote control
via the REMOTE RJ45 located on the rear panel. The exciter has a built-in WEB GUI which requires
only a standard web browser run by a PC. Simply by entering specified IP address, which is setup in
CONFIG sub-menu, in a browser’s address bar, the login interface will pop up and give user prompts
to input the user name and password. There are two tiers of web interface available. The first “guest”
tier is limited in monitoring and control, allowing users to retrieve information such as SNR and
shoulder measurements, user configuration, and alarms. The guest account is accessed with a user
name and password of "guest" and "guest" (case sensitive). The second “admin” tier provides full
status and control of the exciter and is accessed with a username and password of “anywavecom" and
"anywavecom" (case sensitive).
2) "STANDARD" is used to select between different TV standards, the default value is “AT SC ”. There is
also an option to support NTSC and PAL if the analog TV option is installed.
3) "UPGRADE" is a reserved mode to perform an upgrade of the code inside the exciter unit.

Note:
1) "PCRL" in Advanced User Menu contains 3 bits. Its default value is 1 which means both PCR
function and NULL packet deletion is turned on. It’s only applicable in Legacy mode. In MH mode,
all input streams remain untouched.
a) Bit2 is the switch of Insert-NULL-Packet.
It's not used now (reserved) because when TS rate is lower than desired rate and FIFO is Almost
Empty (less than 2.5% of its capacity), if the system does not insert NULL packets into the
stream automatically, the whole FIFO will be reset and lose more useful bytes.
b) Bit1 is the switch of Delete-NULL-Packet.
When value is "0":
If FIFO is Half Full (higher than 50% of its capacity), then the system will DELETE all new
incoming NULL packets from the stream automatically, until FIFO is less than 50%.
When value is "1":
If the FIFO is Half Full, the system will NOT DELETE any new coming packets.

c) Bit0: The switch of Program Clock Reference Correction function
"1" means PCR function is ON;
"0" means PCR function is OFF
2) "Sw_Up" and "Sw_Down" are a pair of switches which control the "Slow_Up / Down" function. If
"Sw_Up" is "ON", when there is a power raise, it will go up gradually. Likewise if "Sw_Down" is
"ON", when there is a power decrease, it will go down gradually too. This "Slow Up / Down"
function is designed for safety consideration and to prevent the transmitter connected from any
possible damage due to the dramatic change of power.
3) SW RT establishes the RF ramp up time, with larger numbers producing a slower ramp to full output
power.
4) “POWER_MAX” is used to set the maximum level of RF output. The default value is +5 dBm, which
means the adjusted range of RF output is -25 dBm ~ +5 dBm.

Note:
1) "PDT" is the pre-set time for the ADPC function which ranges from 0x0 to 0xF, and recommended
value is 0x5 which means about 7 minutes in "UPDATE3" part and about 10 minutes for the entire
ADPC process (all 4 steps together).
2) "CFR" is the pre-set crest factor reduction level which ranges from 0x0 to 0xF. The lower the
parameter's value is, the harder the reduction of crest factor will be. A value of 0xF will bypass the
whole CFR function (No reduction at all).
Note: If ADPC (Pre-correction) is ongoing, the system will disable automatically the CFR
function (clipping) and will only resume the function after ADPC is finished.
3) "ADPC" here has the same function as that in control mode (default user menu) but separates into 3
steps. And the control here and there (default user menu) sync up to each other. All 3 steps still have
to be run in strict sequence to get a complete compensation done. However going step by step
provides an opportunity to monitor each step's performance more closely. Among all 3 steps,
"UPDATE1" is to compensate the linear distortion before band-pass filter, and "UPDATE2" is for the
linear distortion after band-pass filter. "UPDATE3" is for both linear and non-linear distortion in the
whole transmitting system (including both the power amplifier and the band-pass filter). Performing
an “UPDATE” executes the following ADPC correction steps in the following order -> “ U P D AT E 1 ” ,
“UPDATE2”, “UPDATE3”, and “U P D AT E 2 ” .
4) "FSSI" is and indicator of feedback signal strength and its range is from 0% to 100%.
At +5 dB level, FSSI=100%.
At -5 dB level, FSSI=75%
At -15 dB level, FSSI=50%
At -20 dB level, FSSI= 25%
*The readings listed above are typical values. There may be variations on different frequencies or
different units. Overall the recommended level of feedback signal is -15 dBm to -5 dBm, which

Version 1.4 05/23/2014 Page 19 of 35
roughly corresponds to an ideal FSSI signal strength in the range of 40-60%. When FSSI is less than
20% or higher than 75%, the reading will keep flashing, indicating the feedback level may need to be
adjusted.

Note:
1) "TIME": The maximum times of Auto Correction.
When "TIME"="0": Auto Correction function is turned off.
When "TIME"="N": Auto Correction function will run no more than N times after exciter boots up.
When "TIME"="MAX": Times of Auto Correction function is unlimited.
2) "A_SNR" and "A_IMD": Absolute thresholds of triggering an Auto Correction.
If "ADPC" is "HOLD", and current average SNR≤A_SNR or LID ≤A_IMD or UID≤A_IMD, then
exciter will run a complete NEW auto ADPC correction as long as "C_T" ≥1.
3) "R_SNR" and "R_IMD": Relative thresholds of triggering an Auto Correction.
If "ADPC" is "HOLD", and current average SNR≤(M_SNR-R_SNR), or LID ≤(M_IMD-R_IMD) or
UID≤(M_IMD-R_IMD), then exciter will run an auto ADPC correction (NEW or Continued) as long
as "C_T" ≥1. The type of correction (NEW or Continued) is decided by setting of "DPD"'.
4) "DPD":
When "DPD"="NEW": The current curve is cleared first then the exciter starts a complete NEW
ADPC process based on NO pre-stored curve.
When "DPD"="CON": The current curve is kept and then the exciter starts a Continued ADPC
process based on last saved curve.
"CLR": Clear the last saved curve manually.
5) "C_T" (Read-Only): It’s the current Auto Correction times counter. Its maximum value equals to
"TIME". If an AUTO ADPC has been run successfully, the value will be reset to "TIME", otherwise it
will deduct 1 automatically. When "C_T"="0", exciter is not able to start Auto Correction any more.
