Model 43P Specifications
Operation
There is a PUSH ON/PUSH OFF switch on the right side of the meter
housing as you face the unit. To read peak power:
1. Push the switch in.
2. Notice that the red LED is lit. The unit is now ready to
indicate peak power.
To read CW power (no AM modulation):
1. Push the switch again to the OFF position.
2. Notice that the red LED is no longer illuminated. The
unit will once again function to indicate CW power.
Peak Detector Response
The electrical time constant of the peak detector circuit is set at one second,
although the actual response time may be slightly longer than this due to
meter damping. Therefore, a short delay may be noticed between the time
that the transmitter is energized, and the meter reading stabilizes. This delay
RF Frequency Range 0.450-2700 MHz. depending on element selected.
RF Power Rating 100 mW to 10kW, depending on element selected.
