Using the Scope Functions

Making a Measurement

Model N6705 User's Guide
The DC Power Analyzer's scope function is similar to a bench
oscilloscope, displaying output voltage and current signals as a
function of time. It has controls that select which outputs and
functions to display, front panel knobs that adjust gain and offset,
and configurable triggers and markers.
You can configure the Scope View to display voltage or current
waveforms for all outputs. Power waveforms can only be displayed
on Agilent Models N676xA and N678xA SMU, as these have
simultaneous voltage and current measurement capability (see
chapter 1, "Power Module Features"). As explained under "Scope
Horizontal", the maximum sampling rate of the scope varies,
depending on the number of waveforms that are displayed. Note that
in the Scope View there is only one time-base and trigger
configuration for all outputs.
In the following measurement example, an output turn-on sequence
is displayed using the oscilloscope. The oscilloscope measures the
actual voltages as the outputs turn on.
Step 1 – Program the output voltage and current values:
In Meter View, set the output voltage and currents of all four outputs
of the DC Power Analyzer to 10 volts and 1 ampere. This is described
in chapter 3 under "Controlling the Outputs".
Step 2 – Configure the output turn-on sequence:
Configure the output turn-on sequence as described in chapter 3
under "Configuring a Turn-On/Turn-Off Sequence". Note that you will
only need to configure the Turn-on delays, not the turn off delays.
The turn on delays for the output channels are as follows:
• Output 1: 10 ms
• Output 1: 20 ms
• Output 1: 30 ms
• Output 1: 40 ms
