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.

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

	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.

2Use the CALIBRATE menu to adjust the displayed amplitude at each setup to match the measured amplitude and enter the value.

3Perform the Function Gain and Linearity Verification procedures on page 56.

AC Amplitude Adjustment (High-Z)

The function generator stores twenty-two calibration constants related to HIGH Z output, and sixteen calibration constants related to 50W output. The constants are calculated from the adjustment value entered. The cal- ibration constants are stored following completion of setup 22 (HIGH Z output) and the calibration procedure may be aborted after that point. No calibration constants are stored if the procedures are aborted at any other setup.
