3110 HELP FILES – SECTION 4
4.6.1 Installing the Attenuator
Connect the attenuator’s BNC male end to the
Signal Out BNC female connector on the front of
the 3110.
Connect a BNC cable to the female end of the at-
tenuator, and then connect the cable to the unbal-
anced BNC input on the amplifier.
If using, connect a transformer to the amplifier
outputs.
4.6.2 System Calibration
When the attenuator is used, System Gain must
be recalibrated. This allows the 3110 to adjust its
output levels to deliver the required levels at the
system output.
To adjust the 3110’s System Gain setting complete
the following steps:
1. Press the Settings button from the 3110’s main
window, and then select the System Calibration
tab.
2. If desired, adjust the 3110 Output Voltage from
the default setting of 1 Vp.
3. Connect an oscilloscope to the DUT (load at
the system output).
4. Press the Run Calibration Test button to run
the Calibration Test.
5. When the System Calibration testing is com-
pleted, press the Save button to save the new
System Gain setting and return to the 3110’s
main menu.
4.7 Shutdown Procedure
IMPORTANT: Any powered amplifiers that are
connected to the 3110 must first be disabled
before shutting down the 3110 or DSR System.
Failure to follow the proper shutdown procedure
can result in damage to the amplifiers or any con
-
nected load/DUT.
Complete the following to safely shut down a 3110/
amplifier combination or DSR System:
1.
Make sure all amplifiers connected to the
system are disabled. To quickly disable AE
Techron amplifiers, press the Stop button on
the front panel of any amplifier to place all
connected units in Standby mode. Or, you can
turn the amplifier(s) OFF using the amplifier’s
power switch or breaker. Consult the amplifier
or DSR Series Operation Manual for amplifier
power switch location. For non-AE Techron
amplifiers, consult the product instructions to
determine the best method for disabling those
units.
2.
DSR Systems:
After all amplifiers have been
disabled, turn the system OFF by pressing the
System Power button.
Stand-alone 3110s
with attached amplifiers:
Place the 3110’s
front-panel power switch in the OFF (O) posi
-
tion. Then use the amplifier’s power/breaker
switch to turn off each amplifier in the system.
3.
Stand-alone 3110s
that do not have any
amplifiers or load attached can be safely shut
down by simply pressing the 3110 front-panel
power switch.
