Oscilloscope Adjustment
This section explains how to adjust the VirtualBench oscilloscope. You can choose to perform
these adjustment procedures with or without performing the verification procedures first.
Note
NI recommends repeating the verification procedures after you perform these
adjustment procedures. Re-verification ensures that the instrument you have
calibrated is operating within specifications after adjustments.
Note
Allow the VirtualBench to warm up for at least 30 minutes before adjusting.
To adjust the Oscilloscope accuracy perform the following steps:
Note
In this procedure, the 50 Ω BNC terminator is only needed for the VB-8012.
The VB-8034 and VB-8054 use an internal 50 Ω BNC terminator during calibration.
1.
(VB-8012)
Connect a 50 Ω BNC terminator to Oscilloscope channel 1, as shown in
Figure 23.
(VB-8034/8054)
Ensure there are no cables connected to any oscilloscope channels.
