Programming Overview
NOTE: This programming manual is written exclusively for Anritsu Site Master Models S331D and
S332D. For information on firmware upgrades, contact your local Anritsu Service Center. Commands
listed in this manual are not all backward-compatible with earlier Anritsu models.
General Description
The Site Master must first be set into “remote” mode for communication with a computer. Remote mode differs from normal
repetitive sweep and single-sweep modes. During remote mode, the Site Master suspends normal operations and attends to
the serial port. The front panel display indicates when the Site Master is in remote mode.
Once in remote mode, a series of control bytes and associated data are sent to the Site Master to perform various functions
and activities. The serial port supports virtually all features accessible from the keypad with the exception of the printer. The
printer requires connection to the same 9-pin connector on the Site Master rear panel used for remote communication.
To complete the communication session, send the control byte to exit remote mode and the Site Master will resume normal
operations. You may also exit the remote mode by pressing the ESCAPE/CLEAR key on the Site Master front panel.
Interface Cable Installation
The Site Master is a DTE-type serial device. Communication between the Site Master and a PC is accomplished over a null
modem serial cable provided with the Site Master (Anritsu part number 800-441). Connect the cable to the Serial Interface
connector on the Site Master test connector panel and to the appropriate COM port connector on the PC.
Serial Communication Parameters
The Site Master begins communication at 9600 bps when first powered on. It uses no parity bits, 8 data bits, and 1 stop bit
(N-8-1). No hardware handshaking is used. The Set Baud Rate Control Byte #197 (C5h) serial command can be used to
change the baud rate to 19,200, 38,400, 56,000 or 115,200. An invalid setting returns the rate to 9600.
Communications Error Checking
Since there is no hardware handshaking, byte level error handling must be done by the controlling program. Use the expected
number of response bytes (listed in the control byte description section of this manual) when waiting for feedback from the
Site Master. For data streams going to the Site Master, the “watch dog timer” protects against interrupted transmissions by
aborting a control byte sequence if the inter-byte time limit is exceeded.
Parameter Validation
The Site Master validates input parameters for each control byte sequence. If the input parameters are out of range or invalid,
the Site Master notifies the computer by sending Parameter Error Byte #224 (E0h). The Site Master discards the received
data and waits for the next control byte.
Entering Remote Mode
Send the Enter Remote Mode Byte #69 (45h) to the Site Master to enter remote mode at the end of the current sweep. Send
the Enter Remote Mode Immediately byte #70 (46h) to enter remote mode in the middle of a sweep.
The Site Master serial port buffer is one byte wide. No internal buffer exists, so waiting for the response from the unit is es-
sential. If the Site Master is not in remote mode, sending a second byte overwrites the original byte commanding it to enter
remote mode. If control byte #69 is sent, the Site Master will enter remote mode at the end of the current sweep. If control
byte #70 is sent, the unit will enter remote mode as soon as it receives the byte. This means that data stored for the current
sweep may be incomplete. Once a response string is received from the Site Master, the unit is ready to accept additional con-
trol bytes.
Site Master PM 1

Exiting Remote Mode
To exit remote mode, send the Exit Remote Control byte #255 (FFh) to the Site Master. The Site Master sends a response
byte of 255 (FFh) then exits remote mode. Remote mode can also be exited by pressing the ESCAPE/CLEAR front panel
key.
Remote Mode Changes to Site Master Operating Parameters
System parameters changed during remote mode remain changed for normal operation after the unit exits remote mode.
However, the changes are not automatically written to the non-volatile EEPROM. Turning off the Site Master power erases
the changed settings.
To retain the changes, the setup must be saved to one of the setup memory locations. Use either the run-time setup location 0,
(which holds the power-on defaults) or one of the nine other setup locations. Control byte #64 (40h) sets the auto-save flag
which commands the Site Master to automatically save the changes to the run-time setup location upon exiting remote mode.
See the Site Master User’s Guide or information in this manual on control byte #18 (12h) for further details.
Write Cycle Limitation of EEPROM
The EEPROM, used to store calibrations, setups and traces has a guaranteed lifetime of at least 100,000 write cycles and an
unlimited number of read cycles. The write cycle limitation is for a specific location. For example, setup #1 can be stored
100,000 times and setup #2 can be stored 100,000 times, etc. Because of this, the Site Master does not automatically store the
changed system parameters to the EEPROM. Be aware of the EEPROM write cycle limitation when programming the Site
Master and keep the number of write cycles to a minimum.
Documentation Conventions
Throughout this manual, the following conventions will be observed:
Numeric Representation
Hexadecimal numbers are represented with the suffix h. For example, the decimal number 255 is represented in hexadecimal
as FFh.
Binary numbers are represented with the suffix b. For example, the decimal number 2 is represented in binary as 10b.
Decimal numbers are represented with the prefix #when referring to a control byte (command byte) and without a prefix or
suffix in all other cases.
Bit Positions
When enumerating bits in a byte, bit 0 will always be the least significant bit (LSB).
Mode References
The term “VNA” in reference to a command denotes Return Loss, SWR, Cable Loss and DTF modes. The term “SPA” in
reference to a command denotes Spectrum Analyzer mode. All other modes are referenced individually.

Control Byte Descriptions
Setup System – Control Byte #1 (01h)
Description: Sets system status flags and switches. The current value of the flags can be obtained by executing command
#29, Query System Setup, and parsing the values from the appropriate bytes. The Site Master acts on the entire byte. So, the
state of each of the bits must be defined every time the command is issued. See control byte #29 (1Dh) response byte 170
(VNA mode) or response bytes 275 and 276 (SPA mode) for current Site Master configuration.

Set Site Master VNA Marker – Control Byte #5 (05h)
Description: Sets an individual marker position and status in the current VNA measurement mode. See Control Byte #102 to
set markers in Spectrum Analyzer mode.
The Site Master sets the position of a marker by its relative position on the graph. The lowest position is 0 at the start
frequency (or distance). The highest position is the data point number at the stop frequency (or distance). For example, for a
resolution of 130, the first frequency is at position 0. The last frequency is at 129.
To calculate the data point from a frequency (or distance):
point = ( resolution–1)*(marker freq – start freq)/(stop freq – start freq )
See control byte #29 (1Dh) response bytes 44 to 55 for current frequency markers.
See control byte #29 (1Dh) response bytes 138 to 149 for current distance markers.

Set Site Master VNA Single Limit – Control Byte #6 (06h)
Description: Sets the position and On/Off status of the Single Limit Line for the VNA modes. See control byte #103 to set
the single limit for spectrum analyzer mode.
The single limit is a single, horizontal line. It can be set to On/Off in any Site Master mode. If Limit Beep is set to ON, the
Site Master will give an error beep when sweep data appears above the limit line in SWR or Return Loss mode, or when
sweep data appears below the limit line in Cable Loss mode.
The single limit and multiple limit types are mutually exclusive. That is, setting the single limit ON automatically turns
multiple limit lines OFF. See control byte #112 (70h) for information about multiple limits. See control byte #29 (1Dh)
response bytes 56-59, and byte 164 for current Site Master configuration.

Minimum value sent is 0 which represents 0.0 dB
SWR:
Limit is in thousandths (of ratio), so it should be sent as ( ratio * 1000 )
Maximum value sent is 65530 which represents 65.53
Minimum value sent is 1000 which represents 1.00
Set DTF Parameter – Control Byte #7 (07h)
Description: Sets Distance to Fault parameters.
Be aware using this control byte. The distance to fault parameters are all inter-related. Consequently, the control byte must
change all of those parameters at the same time to properly set them.
Enter Start and Stop distances in hundred-thousandths of a meter or foot (12.34m would be sent as 1234000).
Relative Propagation Velocity is in hundred-thousandths (a Relative Propagation Velocity of 0.850 will be sent as 85000).
Cable Loss is in hundred-thousandths of dB/m or dB/ft (–0.345 dB/m would be sent as 34500).
See control byte #29 (1Dh) response bytes 130-137 (Distance), 150-157 (Propagation Velocity & Cable Loss) for current Site

Set Time/Date – Control Byte #8 (08h)
Description: Sets the current time and date.
This Time/Date is stamped into all stored sweeps (for users’ reference).
The Site Master stores bytes as ASCII text. Recommended time form is “hh:mm:ss” (hour:minute:sec). Recommended date
format is “mm/dd/yyyy” (month/day/year).
The current time setting can be found by using control byte #33 to recall trace 0 and examining response bytes 31-38.
The current date setting can be found by using control byte #33 to recall trace 0 and examining response bytes 21-30.

Serial Port Echo On/Off – Control Byte #10 (0Ah)
Description: Sets the serial port echo mode On/Off.
Serial Port Echo Mode uses the single sweep mode (see control byte #11 (0Bh)). At the end of each sweep cycle, the Site
Master sends a Sweep Complete Byte #192 (C0h) to the serial port.
This mode activates once the Site Master exits from the remote mode. Serial Port Echo status can’t be saved to or recalled
from saved setups. Cycling power resets the Serial port echo status to Off.
The Serial Port Echo Mode allows run-time handshaking between the Site Master and computer by doing the following:
1) Enter remote mode. Set Serial Port Echo Mode On. Exit remote mode.
2) The Site Master sweeps once and then sends the Sweep Complete Byte.
3) After you receive it. Enter remote mode. Recall sweep 0 (last sweep trace in RAM).
4) Exit remote mode. Send Sweep Triggering Byte #48 (30h) and wait for the next sweep cycle.
5) Repeat steps 2-4

Site Master VNA Single Sweep Mode On/Off – Control Byte #11 (0Bh)
Description: Enables or disables the Single Sweep Mode during Site Master VNA modes of operation. For Single Sweep
Mode during Spectrum Analyzer mode of operation, see control byte #108 (6Ch). Single Sweep Mode activates once the Site
Master exits from the remote mode.
When the Site Master returns to local mode, the Site Master stops sweeping, waits for either the Run/Hold Key of the Site
Master keypad or triggering byte #48 (30h).
Site Master also checks for the Enter Remote byte #69 (45h) at the end of each sweep. If present in the buffer, Site Master
returns to remote mode.

Watch-Dog Timer On/Off – Control Byte #12 (0Ch)
Description: Enables or disables the Watch-dog timer. Default is Disabled.
The Site Master incorporates a watch-dog timer for higher reliability in serial communication. In selected control bytes (see
Control Byte Summary), the Site Master checks for the time interval between each byte received from the computer. If the
time interval exceeds the set time limit (0.5 sec), the Site Master notifies the computer by sending Time-out Byte #238 (EEh).
The Site Master discards the data it just received and then waits for the next control byte sequence.

Sequence Site Master Calibration – Control Byte #13 (0Dh)
Description: Initiates a calibration step. The Site Master must be calibrated to give accurate measurements.
The command sequence must be sent in correct order. i.e. Open -> Short -> Load. You can also abort the calibration by
command – “Abort” before the command - “Load” is sent. Once command - “Load” is sent, calibration is completed, and the
old calibration data is lost.
The unit under test returns #255(FFh) upon receiving the command, and return #240 (F0h) when the calibration of the
connected component is completed, then waits for further commands to complete the whole calibration process.
This command is designed to be executed step by step: open, short, load. Issuing any other command during this command
sequence will cause undesired results.
