Agilent Technologies E1441A Function Gain and Linearity Verification, Service Procedures

Function Gain and Linearity Verification

This test verifies the output amplitude accuracy specification for sine wave, triangle wave, ramp, and square wave outputs.

Set the function generator for each output indicated in the table below. Use a DMM to measure the function generator ACrms output voltage. Compare the measured results to the test limits shown in the table. This is a HIGH Z output termination test.

		Agilent E1441A				Measurement
	Function		Out	Ampl	Freq	Nominal	Error
			Terma
Q	Sine wave		HIGH Z	7.0 Vrms	1.0 kHz	7.0 Vrms	± 0.07 Vrms
	Sine wave		HIGH Z	5.7 Vrms	1.0 kHz	5.7 Vrms	± 0.057 Vrms
	Triangle wave		HIGH Z	5.7 Vrms	100 Hz	5.7 Vrms	± 0.057 Vrms
	Ramp wave		HIGH Z	5.7 Vrms	100 Hz	5.7 Vrms	± 0.057 Vrms
Q	Square wave		HIGH Z	10.0 Vrms	100 Hz	10.0 Vrms	± 0.1 Vrms
	Square wave		HIGH Z	8.0 Vrms	100 Hz	8.0 Vrms	± 0.08 Vrms

a.The E1441A has a fixed output impedance of 50 Ω on the "Output" terminal. Use the OUTPut:LOAD 50 INFinity MIN MAX command to set the output termination. HIGH Z assumes no load on output. 50 Ω assumes a 50 Ω ± 0.1 Ω load on output.

DC Function Offset Verification

This test verifies the DC offset and DC output specifications.

Set the function generator for each output indicated in the table below. Use a DMM to measure the function generator DCV output. Compare the measured results to the test limits shown in the table. This is a HIGH Z output termination test.

Q	DC Volts	HIGH Z	10.0 VDC	10.0 VDC	± 0.20 VDC
	DC Volts	HIGH Z	-10.0 VDC	-10.0 VDC	± 0.20 VDC

a.The E1441A has a fixed output impedance of 50 Ω on the "Output" terminal. Use the OUTPut:LOAD 50 INFinity MIN MAX command to set the output termination. HIGH Z assumes no load on output. 50 Ω assumes a 50 Ω ± 0.1 Ω load on output.
