About 4-Quadrant Voltage Amplifiers
The SY-5000 are linear, extremely wideband precision power ampliers. They are ideal for all
applications that require fast changing signals at any purely resistive and inductive loads.
Two selectable operating voltages modes are available for high voltage/low current and low voltage/
high current applications. SY-5001 o󰀨ers in addition switchable gain factors and automatic o󰀨set
control. In case of very low impedance loads, choose the low operating voltage mode to reduce
the power loss and increase the output current.
The devices are equipped with a temperature-controlled, low noise fan. Overtemperature protection,
power-loss calculation and absolute-current monitoring guarantee perfect short-circuit and
overload protection.
The ampliers can be operated via operating elements on the front panel, and are also fully remote
controllable via USB. SY-5001 can also be remote controled via GPIB with SCPI commands.
Firmware updates can be installed by customer at any time.

Cooling Concept and Warm-up
Operation and Safety Concept
Operating Voltages
Provide su󰀩cient space behind and in front of the amplier, that air can circulate through the
device unobstructed. Cool air is sucked through the slots at the left and right side of the front
panel. Allow the amplier a warm-up phase of 30 minutes after switching on for stabilization of
its operating points.
Before the amplication begins, some considerations related to the selection of the operating
voltage mode are recommended for e󰀨ective and safe operation.
The amplier modes have the following operating voltages:
• HIGH mode for high output voltages and low load currents
• LOW mode for low output voltages and high load currents
In order to keep the power loss of the amplifier low, the operating voltage should always be
selected according to the load.
Connecting the Signal Source
Connect the BNC input to a suitable 50Ω source, e.g. the signal output of your IWATSU B-H
analyzer. To fully drive the amplier use an input voltage of ± 2.5V at 50Ω. Use high quality co-
axial cables and connectors to avoid signal problems such as loose contacts.
The input is connected with its reference potential to the protective conductor. Make sure
short signal lines and close sockets do not create any disturbing hum loops when using
an earthed source.
SY-5000 series power ampliers are equipped with various safety mechanisms in order to protect them-
selves. If the amplier self-protection is activated check your application setup, all connections and wiring.
Connecting the Load
The power output of the amplier has a BNC connector. The reference potential of the BNC output is
connected to protective earth. Ensure su󰀩cient contact protection of the cabling to your load. Life-threa-
tening voltages can occur.
The output line is part of the load of the amplier. The inductance of this supply line is added to the output
impedance of the amplier, i.e. the source impedance becomes higher at higher frequencies. Keep the
output lines as short as possible in order to feed as much current as possible into your load.
The SY-5001 is optimized for resistive and inductive loads. Long coaxial lines at the output can
therefore be problematic, as they represent considerable output capacities and make the amplier
unstable. All capacities greater than 300 pF can become critical.

SY-5000 Series
19
The SY-5002 is stable at all complex loads. Since the output impedance of the amplier gets
inductive at higher frequencies, this may lead to a signicant overshoot with predominant capaci-
tive loads. This behavior does not indicate a possible instability of the amplier, but is established
due to an excited series resonant circuit of output and line inductance and connected capacity.
In this case, damping the resonant circuit by series resistors is recommended.
Operational Startup
Operation with wrong mains voltage leads to malfunctions or even destruction of the amplier.
Make sure the mains voltage switch is set to the correct mains voltage before connecting
the mains cable to the amplier. Switch on mains voltage with the switch on the mains
socket. The green mains switch on the front panel illuminates and signals the standby
state. Press this button to switch the amplier on completely, fans start running and the
amplier becomes READY after a short period of time. At startup, the amplier is set
to its initial state, which also can be dened by remote control command. Select best
operating voltage mode for your load and connect it to the signal input of your source.
30 minutes warm-up time is recommended. After warm-up phase press OFFSET to start
o󰀨set compensation. Activate the amplier with the illuminated OUTPUT button to start
signal processing.
Factory default setting is a gain of 60 at HIGH operating voltage for SY-5001. The SY-
5001 already carries out an initial o󰀨set during the switch-on phase. The OFFSET ZERO
LED will light up permanently and indicate a successful o󰀨set adjustment. Press the OUTPUT
button to release the output. The amplier supplies the input signal amplied by the gain factor
as output voltage.
Overload and Overcurrent Protection
The SY-5000 series has several partly interleaved safety mechanisms which protect the amplier against
overtemperature and overload.
At a heat sink temperature of 70°C the amplier switches o󰀨, the READY LED turns o󰀨 and the PRO-
TECTION LED lights up permanently. If this occurs, check air supply and proper operation of the fans.
If the temperature falls below 50°C again, the amplier automatically becomes ready.
The amplier switches o󰀨, if the remotely controllable short-circuit current or constant DC or AC
(>10Hz) current is exceeded, or if permissible temperature-dependent power dissipation is exceeded.
The READY LED is o󰀨 and the PROTECTION LED ashes with 1 Hz. The amplier automatically be-
comes ready after 10 s, but the output is not switched on automatically. In case of a presumed power
dissipation, operation with a low operating voltage should be considered. Further information on which
protection is active can be requested by remote control.
If the PROTECTION LED ashes with about 3 Hz, there is a hardware error. In this case
switch o󰀨 the device and wait at least 1 minute. If errors still occur after the hardware has
been switched on again or occur again during operation, the amplier should be analyzed
at the manufacturer. Do not continue to use the amplier.

Integration into Automated Test Systems, SY-5001
Remote Control
• The commands for the GPIB interface are ASCII commands and follow the IEEE488.2
standard for SCPI commands.
• Entries in []-brackets are optional and can be omitted.
• Commands with ? are queries.
• Each command is valid in its short form (capital letters) as well as in its long form.
The commands are not case sensitive.
The entire functionality of the SY-5001 can be remote controlled via USB, or GPIB interface with SCPI
commands, which makes it ideal in automated test environments. The USB interface is installed as
a virtual COM port at 9600 baud, 8 data bits, 1 stop bit and no parity. For more information see
chapter „USB Service Port“.
Remote adjustment of the amplier settings to the load can greatly facilitate operation with switchable
output, selectable operating voltage and adjustable gain with o󰀨set control. Complete amplier monito-
ring with heat sink temperature, power dissipation and detailed error query enable safe automated test
sequences.
Basic Commands
*IDN? Query of device ID, e.g. „PMK, SY-5001, 18901980-0101, V1.6“.
*OPC? Operation Complete query returns „1“ after all previous commands are completely
executed.
*RST Reset into dened basic state (Gain = 60, Input = o󰀨, Output
Voltage Range Auto = on ), a possible error list is deleted.
*RCL <0...3> Recall previously saved device states.
*SAV <0...3> Save the state of the device under a dened memory number. Memory number
“0” denes the start conguration when the device is switched on.
Gain, Offset Zero and Output Voltage Ranges, SY-5001
Use the GAIN buttons to select the gain of SY-5001. For maximum output voltage, gain 60 must be set,
as the input voltage range is limited to ± 3 V. The maximum output voltage is set by the gain buttons. Other
gain settings may be useful for matching to the signal source. The output noise reduces slightly when the
gain is less than 60. Change the gain to activate automatic o󰀨set adjustment. For rmware V 1.5 or lower
automatic o󰀨set adjustment starts when gain is changed from or to 60. During changeover the output
is switched o󰀨, and automatically on after the o󰀨set adjustment is completed. O󰀨set adjustment can be
triggered at any time by pressing the OFFSET ZERO switch or by remote control command.
In automatic mode, the output voltage mode is adjusted to the gain setting. If gain < 60 is selected, the
output voltage mode is set to LOW. The output voltage mode is set to HIGH when a gain of 60 is se-
lected. Automatic switchover remains active until the output voltage mode is manually set, changed
by remote control, or automatic mode is switched o󰀨. Automatic mode can also be reactivated by
remote control.
