Self calibration adjustment
1. Enter and begin the following setup.
Setup
SCPI command
7
[a]
Self-calibration. The output is disabled.
CAL:SET 7
[a] Constants are stored after completing this setup.
2. To proceed:
a. If your calibration procedures require you to verify the adjustment just made, exit the calibration menu and
perform
DC Offset Voltage Verification
b. If you are making all of the adjustments and then verifying the instrument’s performance, continue with the
next procedure in this section.
Output impedance adjustment
The instrument stores calibration constants for the channels' output impedance. These constants are generated with
and without the post-amplifier attenuator.
1. Set the multimeter to measure offset-compensated, 4-wire Ohms. Set the multimeter to use 100 NPLC integ-
ration. Connect the Ohms Source and Ohms Sense of the multimeter inputs to the channel output as shown
below.
2. Use the multimeter to make a 4-wire resistance measurement at the front panel output connector for each
setup in the following table. The expected measured value is approximately 50 Ω.
Setup
SCPI command
8
[a]
24 dB post-attenuator range
CAL:SET 8
9
[a]
0 dB
CAL:SET 9
[a] Constants are stored after completing this setup.
3. Enter the value measured using SCPI command.
4. There are no specific operational verification tests for output impedance. Continue with the next adjustment pro-
cedure in this section.
