Agilent Technologies E1441A user service DC Output Adjustment

DC Output Adjustment

The function generator stores nine calibration constants related to DC volts output. The constants are calculated from the adjustment value entered. The calibration constants are stored following completion of SETUP 59. No calibration constants are stored if the procedures are aborted at any other setup.

1.Use a DMM to measure the function generator DCV output voltage for SETUP 50 in the following table. These adjustments use a HIGH Z output termination.

Table D-17. DC Output Adjustment Setups

	Nominal Output
SETUP	DC Volts	Adjustment for:
50	- 8.0 VDC	Negative offset gain
51	8.0 VDC	Positive offset gain
52	0.0 VDC	AM offset
53	0.0 VDC	2 dB Pre-attenuator offset.
54	0.0 VDC	4 dB Pre-attenuator offset.
55	0.0 VDC	6 dB Pre-attenuator offset.
56	0.0 VDC	8 dB Pre-attenuator offset.
57	0.0 VDC	10 dB Pre-attenuator offset.
58	0.0 VDC	12 dB Pre-attenuator offset.
59	0.0 VDC	14 dB Pre-attenuator offset.

2.Send the CAL:VALue <measured Vdc> to the function generator.

3.Send the CAL? command to the function generator to initiate the calibration.

4.Repeat steps 1, 2 and 3 for SETUP 51 through 59.

5.Perform the “DC Function Offset Verification” on page 168.
