4 Set the synthesizer to deliver a 3 V rms sinewave at a frequency of
2 MHz. Adjust the synthesizer's output voltage until the voltage displayed on
the multimeter is within 0.2% of the voltage recorded on Line A. Record the
synthesizer's voltage setting on Line C of the Adjustment Record.
5 Set the synthesizer to deliver a 3 V rms sinewave at a frequency of
8 MHz. Adjust the synthesizer until the voltage displayed on the multimeter is
within 0.2% of the voltage recorded on Line A. Record the synthesizer's
voltage setting on Line D of the Adjustment Record.
6 Set the synthesizer to deliver a 1 V rms sinewave at a frequency of
100 kHz. Replace the 3 V thermal converter with the 1 V thermal converter.
Record the exact DC voltage measured by the multimeter on Line E of the
Adjustment Record.
