*The standard 1-2-5 sequence in the 54722A plug-in, which is selected by the
mainframe’s front-panel knob, does not correspond exactly to the attenuator ratios in
the hardware. Refer to the HP 54722A Attenuator Plug-in User’s Reference for more
information about the attenuator ranges.
Use the HP 54711A plug-in when:
•
The signal is repetitive, and you are using the equivalent-time sampling
mode.
•
You need high equivalent-time bandwidth.
•
You can use external triggering, and you need high trigger bandwidth.
•
You can give up logic triggering.
Use the HP 54712A plug-in when:
•
The signal is repetitive, and you are using the equivalent-time sampling
mode.
•
The signal happens once or infrequently, you are using the real-time
sampling mode, and the input signal does not contain any frequency
components above 500 MHz.
•
You need internal triggering.
