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.

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 k 400 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.
