Saving Data to a USB Drive
To save the ripple voltage readings to a thumb drive, start by
inserting a USB thumb drive into the USB port on the left side
of the front panel. Press the MENU key. Select Reading Buffers,
press the desired buffer, and then press Save to USB. You can
customize the name of the file. The data will be saved in the
.csv format so it can later be downloaded and imported into a
spreadsheet. TIP: Press the HOME and the ENTER keys on the
front panel at the same time to save a screen capture to a USB
thumb drive.
Setting Up the Ripple Voltage
Measurement using SCPI Commands
The following SCPI command sequence will perform the exact
same ripple voltage measurement as that performed using the
front panel controls. At the end of the command execution,
you will see the same waveform displayed on the front panel as
shown in Figures 3 and 4 .

• Reset the Model DMM7510.
• Set the instrument to measure
digitize voltage.
• Set range to 10V.
• Set the input impedance to 10GΩ.
• Set the sample rate to 1e6.
• Enable automatic aperture.
• Set the sample count to 100.
• Set def buffer1 to store 100 points.
• Clear d ef bu ffer1.
• Digitize the signal.
• Read the first 100 measurement
and relative timestamp values from
defbuffer1.
Setting Up the Ripple Voltage
Measurement Using TSP Commands
The following TSP script is designed to run from Keithley’s Test
Script Builder (TSB) software. TSB is a free software tool that
can be downloaded from Keithley’s website (www.keithley.com).
By default, the Model DMM7510 is configured to use the SCPI
command set. You must select the TSP command set before
sending TSP commands to the instruments. Follow these steps to
change the command set: Press MENU -> Settings -> Command
Set. Select TSP commands.
Like the SCPI commands, these TSP commands will perform
the exact same ripple voltage measurement by configuring the
sample rate to 1MS/s and the sample count to 100 using the
digitize voltage function. The same waveform shown in Figures 3
and 4 will be displayed on the front panel at the end of the script
execution.
