4 Calibration Procedures
92 Keysight 33210A Service Guide
AC Amplitude (high-impedance) Adjustment
The function generator stores a calibration constant for each high-impedance
attenuator path. The gain coefficient of each path is calculated using two
measurements; one with the waveform DAC at + output and one with waveform
DAC at – output. The setups, therefore, must be performed in pairs.
1 Connect the DMM as shown below.
2 Use the DMM to measure the dc voltage at the front-panel Output connector
for each setup in the following table.
Setup
Nominal Signal
DC level
13 +0.015 V Output of -30dB range
14
[a]
-0.015 V Output of -30dB range
15 +0.05 V Output of -20dB range
16
[a]
-0.05 V Output of -20dB range
17 +0.15 V Output of -10dB range
18
[a]
-0.15 V Output of -10dB range
19 +0.50 V Output of 0dB range
