Calibration Testing Procedures
Test Bandwidth
1 Connect the N2790A output to CH1 of the oscilloscope.
2 Connect adaptation 2 to the 81150A function generator output.
3 Connect the red N2790A probe tip to the red banana jack.
4 Connect the black N2790A probe tip to the black banana jack.
5 Load the appropriate setup file.
6 Verify the value complies with the oscilloscope limits listed in the table
below for each output signal at each probe setting.
7 Record the value displayed on the oscilloscope in the Calibration Test
