3.2
How to use the EASYFIX quick fastening lug
See diagram § 6.3
Arrange the two elements to be assembled, taking care to correctly place the centring studs
opposite the holes
Simultaneously tighten the two knurled knobs
3.3
Connecting the modulator to the ORITEL CF 204A power supply unit
Prior to energisation (see § 6.2):
1. Connect the free end of the power supply BNC lead for the pin diode modulator-cum-attenuator to the
female BNC connector
3. Press the network push button
4. Energise the power supply unit.
5. Adjust the modulation level of the microwave signal using the control knob
The microwave energy supplied by the Gunn oscillator can be amplitude modulated by a square
signal with a 1 kHz repetition frequency once the throw-over switch
position. The modulation frequency can then be adjusted by turning the screwdriver slot
6. The microwave signal can or cannot be modulated depending on the position of the throw-over
switch
