These Product Tours are just a structured sequence of web pages. Click the ► button to step through them.
The navigation buttons have the following functions:
|◄ takes you back to the beginning of the current tour
◄ is the same as your browser back button
▲ takes you up a level in the hierarchy
► steps forward to the next page
The drop-lists give another way of accessing the same pages

Bandwidth Control
Switch Position:
FULL
500kHz
2Hz
Nominal Bandwidth:
DC→5MHz
DC→500kHz
DC→2Hz
Risetime:
<70ns

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.
