Operating Instructions
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 tune oscillator frequency to obtain maximum meter indication.
4.Set attenuator and SWR meter range switch as listed in Table 4 and verify that SWR meter indicates within limits shown.
