CONTROLS |
|
-
SQL KNOB - This knob turns the RF counter on the tunes the squelch up or down to set the signal strength for reception.
-
RANGE SWITCH - this should be switched to the 1 GHz position for frequencies between 30MHz and 0.8GHz, switched to the 2.8 GHZ position for frequencies between 500 MHz and 2.8 GHz.
-
HOLD BUTTON - This holds the current display and stops the counter from counting.
-
CALIBRATION - This calibration adjustment opening is located on the front panel of the counter. This allows access to the trimmer capacitor that provides about a 10 PPM adjustment range of the time base oscillator. This is not usually necessary but to do so read a signal of a known frequency before adjusting the trimmer for correct frequency display. If you calibrate at 4.1943 MHz or above then the counter will be more accurate.
-
VIBRATION Switch - This switch selects the tone or vibration alert output.
