To select the different counters press:
This field is tied to the
pressing @ COUNT, the current frequency count is copied to the receive field. By pressing the
COUNT button the current frequency count is copied to the generator field.
Note: The count is rounded to the nearest set step size that has been set in the Receive or
Generate field. For example if the frequency count was 10.000123 MHz, and the step size set
for the Receive field is 5 kHz, the frequency copied into the Receive field will be rounded to
the 5 kHz step, so it will be set to 10.0000 MHz.

Your COM3010 contains three different RF
frequency counters. Each frequency counter
has two gate times. The value counted is the
signal presented at the RECEIVE IN jack.
Description
sensitive as the receiver. (<5uV). Good for count-
ing signals +/-7 kHz away from the receiver's set
frequency.
Used for measuring signals in the lower
frequency range of the COM3010. Does not use a
frequency prescaler so accuracy is 1Hz maximum.
Worst case sensitivity of 10mV. Only displays
strongest signal.
Used for measuring signals in the upper
frequency range of the COM3010. Uses a divide
by 10 prescaler, so the maximum accuracy is
10Hz. Worst-case sensitivity of 10mV. Only
displays strongest signal.
