Commands Listed in Alphabetical Order
Arguments
Volt sets the un
its for the speciļ¬ed channel to volts.
Rho sets the units for the speciļ¬ed channel to rho.
Ohm sets the units for the speciļ¬ed channel to ohms.
Examples
TDR:CH3:UNITS VOLT sets the units for Channel 3 to volts.
TDR:CH3:UNITS? might return TDR:CH3:UNITS OHM, indicating that the units
for Channel 3 are ohms.
TDR:INTRate
This command sets or queries the TDR (internal clock) rate. The command se ts
the same parameter as the TRIGger:INTRate command. The internal clock in
the instrument generates a continuous signal with selectable repetition rates of
200 kHz (default), 100 kHz, 50 kHz, and 25 kHz. Sending this command is
equivalent to selecting a value for Internal Clock in the TDR (or Trigger) Setup
dialog box. The internal clock rate is used to synchronize the generation of TDR
step pulses with the subsequent acquisition.

TDR:INTRate?
Related Commands
TRIGger:INTRate
Arguments
NR3 sets the internal clock rate to one of the following: 25 kHz, 50 kHz, 100 kHz,
or 200 kHz. You can input any NR3 value; the instrument will set the internal
clock rate to the closest available setting.
Examples
TDR:INTRATE 100E3 sets the internal clock rate to 100 kHz.
TDR:INTRATE? might return TDR:INTRATE 0.200000000000E+006,
indicating that the internal clock rate is set to the default, which is 200 kHz.
TIMe
This command sets o r queries the time that the instrument can display.
