1.  Module is supported by 86100D DCA-X mainframe and later.
2.  Upgradable from 2 channel to 4 channel after purchase (return to Keysight).
3.  Connector style is the same on all channels and is selected at time of order.
4.  Upgradable from 35 to 50 GHz after purchase (return to Keysight).
5.  Tuned to be –3 dB (± measurement uncertainty) at stated bandwidth(s) using NIST traceable swept-sine test system.
6.  Flex DCA software auto-selects the mainframe or module timebase based on DUT setup.
7.  Defined as the transition time at the output of the remote head. It is calculated by deconvolving the receiver transition time from the measured transition
time when the remote head is terminated with a short. Measured on a negative TDR step.
