AMETEK CTs NetWave
9.7. Filter Box F-BOX
The filter box is a low pass filter that suppresses high frequency content distortions. It is used in situations
where the output noise of the NetWave is too high, i.e. emission measurements.
It is mandatory to be used for tests “Voltage Distortion Spectrum” as per MIL-STD-704 LDC/HDC 103 or MIL-
STD-461 . Test condition A (10 Hz) and B (25 Hz) needs for filter the small distortion signal (< 0.5 V rms) the
additional filter box.
