warming up, connect the Automatic Network Analyzer (ANA) to the
RF input connector.
2. Adjust the ANA frequency for a VSWR measurement between 300
kHz and 1000 MHz. Find and record the maximum VSWR reading in
this range.
3. Find and record the maximum VSWR reading while adjusting the
ANA frequency between 1000 and 2500 MHz.
4. Set up the ANA to measure reflection coefficient from 300 kHz to
2500 MHz frequency range. Plot the results for use during error anal-
ysis.
5. Turn off the network analyzer and disconnect it from the RF input
connector.
WARNING
HIGH VOLTAGE
Electrical shock hazard. Be careful when working near high voltage cables. Always have
someone near capable of rendering aid.
6. Hook up the AC Power Source output cable the RF input connector.
7. Adjust the AC Power Source to each of the voltages listed below. For
each voltage setting, wait for the Calorimeter to reach a stable RF
power (Watts) reading. For each voltage setting, read and record the
power indications on the Calorimeter and the AC Power Standard.
22.4, ±0.5 volts RMS, 60 Hz
35.4, ±0.7 volts RMS, 60 Hz
70.7, ±1.4 volts RMS, 60 Hz
100.0, ±2.0 volts RMS, 60 Hz
8. Adjust the AC Power Source for 0.0 volts RMS. Allow the Calorimeter
to run until the ∆ T is less than 0.040°C.
9. Turn off the power to the equipment.
