Itech IT9121 Power Meter ( BK Precision 5335B)

Dear EEV community,


Has anyone used these instruments to measure power for high frequency drive circuits? I need to measure
Power for 18 kHz to 50 kHz AC signals. The voltage ranges from 100 to 400 Vac, the power is under 10 watts.


Thank everyone,
Mike

The IT9121 power meter can provide the maximum input of 600 Vrms and 20 Arms and measurement bandwidth of 100 KHZ, and can be easily used for measuring the voltage, current, power, frequency, harmonics and other parameters

Should be OK. Assuming we are talking 50kHz sine. You might want to check the accuracy spec at that low of a current though.
