Check DC Gain Accuracy
This test checks the DC gain accuracy.
1.
Connect the oscilloscope to a DC voltage source. If using the Fluke 9500
calibrator, connect the calibrator head to the oscilloscope channel to test.
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. The Termination (input
impedance) is set to 1 M
Ω
and channel 1 input is selected.
NOTE.
50
Ω
termination testing (steps 4 through 11) is required only for
MSO4104B, DPO4104B, MSO4104B-L, DPO4104B-L, MSO4102B-L,
DPO4102B-L, MSO4102B, and DPO4102B models.
1 M
Ω
termination testing (step 14 ) is required for all models.
3.
For MSO4104B, DPO4104B, MSO4104B-L, DPO4104B-L, MSO4102B-L,
DPO4102B-L, MSO4102B, and DPO4102B models, perform steps 4
through 14. For other models, go to step 14 now.
4.
Select 50
Ω
input impedance as follows:
a.
Set the calibrator to 50
Ω
output impedance.
b.
Push the channel 1 button.
c.
Set the
Termination
(input impedance) to
50
Ω
.
5.
Set the bandwidth to 20 MHz as follows:
a.
Push the lower-bezel
Bandwidth
button.
b.
Push the
20 MHz
side-bezel button to select the bandwidth.
