24. Repeat steps 3 to 21 for MSO channel 2.
Note For all inputs, change the Channel input to mso/2.
25.
(VB-8012) Skip to step 28.
26. (VB-8034/8054) Repeat steps 3 to 21 for MSO channel 3.
Note (VB-8034/8054) For all inputs, change the Channel input to mso/3.
27.
(VB-8034/8054) Repeat steps 3 to 21 for MSO channel 4.
Note (VB-8034/8054) For all inputs, change the Channel input to mso/4.

Commit
You have completed adjusting the VirtualBench oscilloscope. It is recommended that a
post-adjustment verification be performed.
Oscilloscope EEPROM Update
When an adjustment procedure for the oscilloscope is completed, the VirtualBench internal
calibration memory (EEPROM) is immediately updated.
If you do not want to perform an adjustment, you can update the calibration date and onboard
calibration temperature without making any adjustments by calling
Cal Set Calibration
Information
.
Oscilloscope Re-Verification
Repeat the Oscilloscope Verification section to determine the As-Left status of the instrument.
Note If any test fails re-verification after performing an adjustment, verify that you
have met the conditions listed in the Oscilloscope Test Conditions section before
returning your device to NI. Refer to Where to Go for Support for assistance in
returning the device to NI.
Function Generator (FGEN) Calibration
Procedure
This section contains the verification and adjustment procedures for the FGEN on the
VirtualBench. The calibration process includes the following steps:
1. FGEN Initial Setup—Set up the test equipment.
2. FGEN Verification—Verify the existing operation of the instrument. This step confirms
whether the instrument is operating within its specified range prior to adjustment.
