Part Two – The Agilent 54622D Mixed-Signal Oscilloscope- Digital Inputs

Features to Try - Turning On the Digital Channels

1) OK, now that we are familiar with the mixed-signal oscilloscope using its analog inputs, now

let's get acquainted with the digital inputs and their controls.

2) First, return the oscilloscope to its “Default” condition by pressing the Save/Recall Hardkey

in the File area of the front panel, then pressing the Default Setup softkey.

3) Next, connect a (compensated) 10X analog probe from channel 1 input to the Probe

Compensator output (probe tip to "Probe Comp", probe ground the the ground connection

immediately above.

4) Press the Autoscale hardkey, and adjust the display so that it looks like the one below (note

that Averaging is being used to remove noise from the waveform):

What we see above is a unipolar squarewave, going from 0 V to 5 V. This sounds like a

digital signal, and we can use it to try out the digital input capability of the mixed-signal

oscilloscope (using just one of the 16 digital input channels).

5) Connect the 16-channel cable (part of the digital probe kit) to the D15-D0 input connector on

the front of the oscilloscope.

6) Connect the D0 lead to the "Probe Comp" output (where the 10X probe tip is still connected).

Now press the D7 Thru D0 hardkey in the digital section of the front panel, and you should

see analog channel 1 on the top of the display, and eight digital channels (D0 - D7) on the

bottom. See the display below:

1 2 ... 10 11 12 13 14 15 16 17 18 19 20 ... 30 31
