Bandwidth Control
Switch Position: FULL 500kHz 2Hz
Nominal Bandwidth: DC→5MHz DC→500kHz DC→2Hz
Risetime: <70ns 700ns 175ms
Aberrations: <±5% <±1% <±1%
Noise (typ*): 6mA rms 3mA rms 1.5mA rms
*This is the noise level for current measurement using the toroid attachment. For PCB track measurement the equivalent noise will depend upon the track width and gain setting but will be similar to the toroid measurement figure for a track width of 0.5mm.
