3. Set the synthesizer to deliver a 3V rms sinewave at a frequency of
100 kHz. Connect the synthesizer, the 3V thermal converter, and the
multimeter as shown in Figure 4. Record the exact DC voltage
measured by the multimeter on Line A of the Adjustment Record.
Figure 4. Characterizing the Adjustment Setup
4. Set the synthesizer to deliver a 3V 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 3V 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 1V rms sinewave at a frequency of
100 kHz. Replace the 3V thermal converter with the 1V thermal
converter. Record the exact DC voltage measured by the multimeter
on Line E of the Adjustment Record.
7. Set the synthesizer to deliver a 1V 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 E. Record
the synthesizer's voltage setting on Line F of the Adjustment Record.
