Performance Tests Procedures
Procedure:
1 Connect the equipment as shown in Figure 8. Calibrate the noise figure meter. Check
the amplifier's noise figure at 100 MHz (or 105 MHz). It should be less than 8.5 dB.
For the HP 8447F option H64 low frequency preamp, check the amplifier's noise fig-
ure at 30 MHz. It should be less than 7 dB.

2 Connect the equipment as shown in Figure 9. Set the sweep oscillator for a fixed, CW
signal at 1300 MHz. Set the signal level out of the oscillator for +10 dBm, read on the
power meter.
3 Disconnect the power meter from the oscillator and connect the oscillator to the
mixer.
4 Set the noise figure meter to measure noise at 100 MHz. Calibrate the meter.
If the noise figure meter being used has a 105 MHz input frequency, set the sweep oscillator
(in step 2) to 1305 MHz.
5 Check the amplifier's noise figure. It should be less than 8.5 dB.
