Adjusting the DC common mode rejection
Equipment
●
R&S RTO oscilloscope
●
DC voltage source, max. output voltage 30 V, floating output, e.g.
HMP4040
●
BNC to 4 mm dual banana adapter
●
BNC to grabber adapter, e.g. Pomona mod. 3789
●
2 mini clips
●
2 leads, 6 cm/2.4 in
●
1 lead, 15 cm/5.9 in
●
Small skrewdriver
Setup
During the following procedure, both signal sockets (positive and nega-
tive) are connected to the Hi output of the DC voltage source. The ground
socket is connected to the Lo output of the DC voltage source.
●
Connect the probe to CH1 of the R&S RTO oscilloscope.
●
Plug the BNC to 4 mm dual banana adapter onto the OUTPUT HI/LO
of the DC voltage source. Ensure that the BNC shield is connected to
LO.
●
Connect the BNC to grabber adapter to the BNC to 4 mm dual
banana adapter.
●
Using a mini clip and 2 leads, 6 cm/2.4 in, connect both signal inputs
of the external attenuator to the grabber. Use both inputs of the mini
clip.
●
Using a mini clip and a lead, 15 cm/5.9 in, connect the ground input of
the external attenuator to the shield of the BNC to 4 mm dual banana
adapter.
