Performance Tests (MSO/DPO5000 Series)
12. Repeat the proc
edure for all remaining channels:
a. Push the front-panel button to deselect the channel that you have already
tested.
b. Push the front-panel button to select the next channel to be tested.
c. Move the DC voltage source connection to the channel input to be tested.
d. Starting from step 3, repeat the procedure until all channels have been
tested.
13. Press the Menu Off button.
Check Offset Accuracy
This test checks the offset accuracy.
1. Connect the oscilloscope to a DC voltage source. If you are using the Fluke
9500 calibrator as the DC voltage source, connect the calibrator head t o the
oscilloscope channel 1.
WARNING. The generator is capable of providing dangerous voltages. Be sure to
set the generator to off or 0 volts before connecting, disconnecting, and/or moving
the test hookup during the performance of this procedure.
2. Push the front-panel Default Setup button.
3. Set the impedance to 50 Ω as follows:
a. Set the calibrator to 50 Ω output impedance.
b. Push the front-panel oscilloscope Vertical Menu button.
c. Set the Termination to 50 Ω.
4. Set the calibrator to 900 mV, as shown in the test record.
5. Set the Bandwidth to 20 MHz.
