Procedure 1. Connect equipment as shown in Figure 4 on page 12 with the attenuator
set to 0 dB attenuation.
2. Set the test oscillator to 0.3 Vrms at 1 kHz.
3. Set SWR meter range to 2 dB (expanded) [or for the 8494G/H to 10 dB
(expanded)] and adjust its bandwidth to center of adjustment range. Fine
