DC Accuracy
The gain of the probe-oscilloscope system and the accuracy of the integrated DC
voltmeter are checked.
Test setup:
●
Probe connected to CH1 of the R&S RTO oscilloscope
●
INPUT HI/LO of the DMM connected to OUTPUT HI/LO of the DC
voltage source by banana leads
●
BNC to 4 mm dual banana adapter plugged onto the banana leads
on the DMM – ensure that BNC shield is connected to LO
●
Signal and ground terminal of the probe connected by mini clips to
the BNC to 4 mm dual banana adapter; make sure that probe ground
is connected to BNC shield
Lead connected to the input socket using a signal adapter, square pin
R&S RTO settings:
●
Horizontal scale = 10 µs / div

Vertical scale = 1.6 V / div
●
Trigger source = Ch1, Trigger mode = Auto, Run cont
