8. Set the synthesizer to deliver a 100mV rms sinewave at a frequency of
100 kHz. Replace the 1V thermal converter with the 0.5V thermal
converter. Record the exact DC voltage measured by the multimeter
on Line G of the Adjustment Record.
9. Set the synthesizer to deliver a 100mV 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 G. Record
the synthesizer's voltage setting on Line H of the Adjustment Record.
10. Disconnect the thermal converter and connect the synthesizer. 50W
resistive load. and multimeter as shown in Figure 5.

11. Set the synthesizer to output 3V rms at 100kHz. Execute the
SCAL 1E5 command. The multimeter automatically performs the
adjustment. When the adjustment is complete, the multimeter returns
to displaying DC voltage readings.
12. Without changing the synthesizer settings, execute the SCAL 10
command as shown on Line B of the Adjustment Record.
13. Set the synthesizer to the voltage and frequency shown on Line C of
the Adjustment Record. Execute the SCAL command as shown on
Line C of the Adjustment Record.
