TDR:CH<x>:UNIts
This command sets or queries the TDR units for the channel specified by x, which
can be 1 through 8 . This is equivalent to checking the ON control for the specified
channel in the TDR Step section of the TDR Setup dialog box and then selecting
the units from the pulldown list for the specified channel. The units of measure
commonly used in TDR are units of rho (r) measured on the vertical axis.
NOTE. These units apply only when the TDR step is on for the specified channel;
when the TDR step is on, the vertical units setting for the specified channel is
overwritten.
