2 Set the U2761A based on the following.

• Load impedance: High-Z

• Function: DC

3 Set the U2761A to each output listed in the table below.

1 Based upon ±2% of offset setting ±10 mV (High-Z).

4 Compare the measured voltages with the test limits shown

in Table 3- 4.

AC Amplitude (High Impedance) Verification

This procedure verifies the accuracy of the AC output

amplitude at frequencies of 1 kHz and 100 kHz, and

establishes reference measurement for the higher frequency

flatness verification procedures.

1 Set the DMM to measure AC voltage. Connect the DMM to

the U2761A as shown in Figure 3- 3.

2 Set the U2761A based on the following.

• Load impedance: High-Z

• Offset: 0 V
