4-25. CALIBRATOR OUTPUT ACCURACY

SPECIFICATION:

Amplitude: - 10 dBm +0.3 dB

Frequency: 35 MHz +400 kHz

DESCRIPTION:

The frequency of the calibrator output signal is measured with a microwave counter. The calibrator output level is measured using a power meter.

Power Meter ...........................................................					H P 435A/B
Power Sensor ...........................................................					H P 8481A

PROCEDURE:

1.Connect spectrum analyzer CAL OUTPUT to frequency counter's 10 Hz - 500 MHz (5m) input as shown in Figure 4-20. Measured output frequency should be 35 MHz k400 kHz.

2.Zero and calibrate power meter. Connect power sensor, through adapter, to spectrum analyzer's CAL OUTPUT and measure power level. Calibrator output level should be - 10 dBm +0.3 dB.
