7 Set the synthesizer to deliver a 1 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 E. Record the synthesizer's voltage
setting on Line F of the Adjustment Record.
8 Set the synthesizer to deliver a 100 mV rms sinewave at a frequency of 100
kHz. Replace the 1 V thermal converter with the 0.5 V 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 100 mV 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. 50 W resistive
load. and multimeter as shown in Figure 3-5.
