Agilent Technologies E1441A user service Function Gain and Linearity Adjustment

Function Gain and Linearity Adjustment

The function generator stores six calibration constants related to function gain and linearity. The constants are calculated from the adjustment value entered. If the calibration procedure is aborted before all setup steps have been completed, no calibration constants are stored.

1.Use a DMM to measure the function generator ACrms output voltage for SETUP 02 in the following table. These adjustments use a HIGH Z output termination.

Table D-12. Function Gain and Linearity Adjustment Setups

	Nominal Output
SETUP	FREQUENCY	AMPLITUDE
02	1 kHz	7.07 V rms	Adjustment for sine wave gain.
03	1 kHz	5.6 V rms	Adjustment for amplitude linearity.
04	100 Hz	5.6 V rms	Adjustment for triangle wave gain.
05	100 Hz	5.6 V rms	Adjustment for ramp gain.
06	100 Hz	10.0 V rms	Adjustment for square wave gain.
07	100 Hz	1.1 Vrms	Adjustment for square wave linearity.

2.Send the CAL:VALue <measured Vac> 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 03 through 07.

5.Perform the “Function Gain and Linearity Verification” on page 168.
