Amplitude
Adjustment
Equipment: DMM, 50S feedthrough termination
1. Configure the Model 3152 as follows:
Function: Sine
Frequency: 1 KHz
Amplitude: 16 V
Remote Commands::RES
:OUTP ON
:FREQ 1E3
:VOLT 16
2. Connect the Model 3152 output to the DMM input through
the 50S feedthrough termination. Set the DMM to AC Volt
measurements and 2 V range.
3. Adjust R44 until the DMM reading is 5.657 V ±20 mV.
4. Change the Model 3152 amplitude setting to 2.0 V.
5. Adjust R44 until the DMM reading is 1.803V ±6 mV.
6. Repeat Steps 4 and 5 until the best result is obtained in
both steps.
Revised 5/98
Offset Adjustment
Equipment: DMM, 50S feedthrough termination
1. Configure the Model 3152 as follows:
Function: Sine
Frequency: 1 MHz
Amplitude: 1.61 V
Offset: +7.19V
Remote Commands::RES
:OUTP ON
:FREQ 1e6
:VOLT 1.61
:VOLT:OFFS 7.19
2. Connect the Model 3152 output to the DMM input through
the 50S feedthrough termination. Set the DMM to DCV
measurements and 10 V range. Record this reading.
3. Change the offset setting to -7.19 V and adjust R85 to
have the exact reading as was recorded in the previous
step (with reversed polarity).
4. Adjust R62 until the DMM reading is -7.190 V ±30 mV.
5. Repeat Steps 3 and 4 until the best result is obtained in
both steps.
