3 Calibration

22 U2761A Service Guide

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

1 1 kHz: Based upon ±1% of setting ±5 mVpp (50 Ω) converted to Vrms for

High-Z.

100 kHz: Based upon ±0.2 dB (2.3%) of setting ±5 mVpp (50 Ω) converted to

Vrms for High-Z.

4 Compare the measured voltage with the test limits shown

in above table, and fill in Table 3- 6 using the following

equation.
