(4) Calibration procedure
Step Procedure
1. Setup the equipment as shown in the figure above. The ambient temperature must be 23°C ± 5°C.
2. Set the Power switch on the rear panel to On and the Power switch on the front panel to the Standby
position. Then, allow the MT8801C reference crystal oscillator to warm-up for 24 hours.
3. Set the Power switch on the MT8801C front panel to On.
4. Apply the standard frequency signal to the external reference input of the frequency counter.
5. Move to the RX Measure screen in the Analog Tester mode on the MT8801C.
6. Set the frequency of the signal generator of the MT8801C to 1 000.000 000 MHz, the level to –28
dBm, and the modulation to off.
7. Adjust the calibration trimmer of the crystal oscillator so that the frequency-counter reading is 1
000.000 000 MHz ±10 Hz.
