   This digital power meter built by idea of OZ2CPU,but  I modified in few points.
I testing my PA's with this type PWR meter.
 

Frequency Coverage: 0-500MHz
RF input level: -60dBm to +30dBm( 1W),up to 10KW with RF coupler!
MENU points:

0:  0dB, no attenuator is mounted 1W max. !
1:  -10dB attenuator is mounted, 10W max. !
2:  -20dB attenuator is mounted, 100W max. !
3:  -30dB attenuator is mounted, 1kW max. !
4:  -40dB attenuator is mounted, 10kW max. !
5:  -50dB attenuator is mounted, 100kW max. !
6: DC Voltmeter, actual and min. and max.
7: RF Powermeter, the default startup screen.
8: SSB PEP Wattmeter, with peak hold and variable decay
9: Return loss with SWR readout, usable with a SWR bridge
10: Calibrate 0 dBm at the selected band
11: Read all calibration values
12: Zero all calibration memories
13: Display update delay 2-80mS, and Peak hold and decay speed
14: About Info, shows software version and so on.

DC Voltmeter: 0-20V positive 20mV resolution,80KOhm  input impedance
Accuracy: < +- 0.5dBm btn 0-500MHz
Power supply: External, 9-15V DC max.200mA
Data output: RS232 to your PC,software modified OZ6ADL DWM102.
.
