
If you perform ChannelSync Cal on multiple gain settings, perform
it first on the 100 mV/div setting, then perform it on other gain
settings (with “Reference Correction” values entered as
appropriate for those other gain settings.)

For the highest possible accuracy across the full input range of the
oscilloscope, a ChannelSync Cal should be performed on at least
one gain setting in each of the following gain ranges:
13-20 GHz ProLink
"A" Inputs
30-45 GHz 2.92mm or 2.4mm
"B" Inputs
<11.8 mV/div 10 mV/div
11.9 to 17.0 mV/div 10.1 to 12.6 mV/div
17.1 to 20.5 mV/div 12.7 to 15.8 mV/div
20.6 to 30.0 mV/div 15.9 to 20.0 mV/div
30.1 to 39.6 mV/div 20.1 to 25.0 mV/div
39.6 to 50.0 mV/div 25.1 to 31.5 mV/div
50.1 to 90.0 mV/div 31.6 to 39.5 mV/div
90.1 to 100.0 mV/div 39.6 to 50.0 mV/div
100.1 to 118.0 mV/div 50.1 to 63.0 mV/div
118.1 to 170.0 mV/div 63.1 to 79.0 mV/div
170.1 to 205.0 mV/div 79.1 to 82.0 mV/div
205.1 to 300.0 mV/div 82.1 to 100.0 mV/div
300.1 to 395.0 mV/div 100.1 to 126.0 mV/div
395.1 to 500.0 mV/div 126.1 to 158.0 mV/div
500.1 to 900.0 mV/div 158.1 to 200.0 mV/div
900.1 to 1000 mV/div 200.1 to 250.0 mV/div

If you add cables or probes to your setup subsequent to running
the ChannelSync Cal, you must manually deskew these items in the
Channel dialog to account for their propagation delays. The values
you provide on the Channel dialog (in the deskew section) are
additional to values shown on the ChannelSync Calibration dialog.
