17 nW* The integrated input noise is measured with a shaded input in the full bandwidth (‘‘FBW’’) setting(referred to 850 nm). The measurement bandwidth is 3 x the upper cut-off frequency at thest
specific gain setting; filter slope is a 1 order roll-off.
The input referred peak-peak noise can be calculated from the RMS noise as follows:
PInput noise peak-to-peak= PInput noise RMS x 6
The output noise is given by:

UOutput noise RMS
UOutput noise peak-to-peak= PInput noise RMS x gain x R= UOutput noise RMS x 6 = PInput noise RMS x gain x R x 6

The integrated noise will be reduced considerably by setting the low pass filter to ‘‘1 MHz’’ or‘‘10 MHz’’ instead of ‘‘FBW’’. This is especially useful for continuous wave (CW) measurements.

Remote Control Operation

GeneralRemote control input bits are opto-isolated and connectedby a logical OR function to the local switch settings. For
remote control set the corresponding local switches to“Remote”, “AC” and “H” and select the desired setting via
a bit code at the corresponding digital inputs.
Mixed operation, e.g. local AC/DC setting and remotecontrolled gain setting, is also possible.
