ADCMT 6253 - Reverse Function; Reverse Operations in DC Sweep Mode

6253 DC Voltage Current Source/Monitor Operation Manual
4.2.3 Operations in Sweep Source Mode
4-24
4.2.3.5 Reverse Function
Turning ON or OFF the reverse function will switch the sweep operation between one-way sweep and
round sweep.
Reverse OFF: One-way sweep
Reverse ON: Round sweep
The linear sweep sweeps as shown below.
Other types of sweeps also begin sweeping backwards to the start value at the stop value when the reverse
mode is set to ON.
The following table shows the measurement and source timings in the sweep source mode with the reverse
mode is set to ON (round sweep).

Generates staircase
waveforms of the number
of steps from the start
value to the stop value,
then sweeps backwards in
the same way from the
stop value to the start
value.
