Calibration for firmware revision A03 and lower
Measuring function generator signal amplitude
The 3Hz function generator signal amplitude must be accurately measured using the digi-
tal multimeter listed in
1.

Front panel manufacturing calibration (firmware revision A03 and lower)
1.
Calibrate step 0 with the following command:
:CAL:PROT:DC:STEP0
Perform the entire remote comprehensive calibration procedure. See
calibration" earlier in this section.
Connect the calibrator to the Model 2790 INPUT jacks as shown in
Select the front input jacks with the INPUTS switch.
Set the calibrator to output a 1V RMS, 10Hz sine wave, then send the following
command:
:CAL:PROT:AC:STEP14 <Cal_voltage>
Here <Cal_voltage> is the actual 10Hz calibrator signal amplitude. If an error is
reported after performing this step, refer to
Connect the function generator to the Model 2790 INPUT jacks as shown in
Figure
17-6.
Set the generator to output a 1V RMS, 1kHz sine wave, then send the following
command:
:CAL:PROT:AC:STEP15 1E3
Send the following commands to set calibration dates, save calibration, and lock
out calibration:
:CAL:PROT:DATE <yyyy>, <mm>, <dd>
:CAL:PROT:NDUE <yyyy>, <mm>, <dd>
:CAL:PROT:SAVE
:CAL:PROT:LOCK
Table
17-13. Proceed as follows:
Connect the function generator output to the digital multimeter INPUT jacks. (See
Figure 17-6
for typical connections.)
Turn on the function generator and multimeter. Allow a two-hour warm-up period
before measuring.
Set the function generator to output a 1V RMS sine wave at 3Hz; measure and
record the signal amplitude.
Install the shorted calibration extender board (see
earlier in this section) in scanner card Slot 1 and select the rear inputs with the
INPUTS switch. Allow three minutes for thermal equilibrium.
