9.
Check that the Frequency measurement reads 1 kHz
10. Repeat these steps to check the other channels on the oscilloscope. Make sure that you set the source in the Add Measurement
configuration menu to use the correct channel before adding the Frequency measurement.
Download and install the latest firmware
Installing the latest firmware helps ensure that your instrument is equipped with all of the best available measurement and analysis
improvements.
Before you begin
Prerequisite: Save any important on-instrument files (waveforms, screen captures, oscilloscope setups, and so on) to a USB drive or
network. The installation process does not remove user-created files, but it is a good idea to back up important files before an update.
Update oscilloscope firmware from a USB drive
Before you begin
Prerequisite: Determine the current version of firmware installed on the oscilloscope (Help > About)
Procedure
1. Open up a Web browser on a PC and go to www.tek.com/product-support.
2. Enter the oscilloscope model number in the search field and click Go.
3. Scroll down the screen and click the Software tab.
4. If the listed available firmware version is newer than what is on your oscilloscope, select and download that file to your PC.
5. Copy the firmware install file to a USB drive.
6. Insert the USB drive into any oscilloscope USB Host port:
7. Power off the oscilloscope and then power on the oscilloscope.
Note: Do not power off the oscilloscope or remove the USB flash drive until the oscilloscope finishes installing the firmware.
The oscilloscope displays a message when it is OK to turn off the oscilloscope.
The oscilloscopes detects the USB drive with the firmware file and starts the installation process. Follow on-screen instructions to
install the firmware.
8. When the firmware install is finished, remove the USB drive and restart the oscilloscope.
To confirm the firmware installation:
a. Tap Help > About in the Menu bar.
b. Verify that the firmware version number listed on the screen is the same version that you downloaded.
Run Signal Path Compensation (SPC)
Run SPC at regular intervals for best measurement accuracy. You should run SPC whenever the ambient (room) temperature has changed
by more than 5 °C (9 °F) or once a week if you use vertical scale settings of 5 mV/div or less.
About this task
Signal Path Compensation (SPC) corrects for DC level inaccuracies in the internal signal path caused by temperature variations and/or
long-term signal path drift.
Failure to run SPC on a regular basis may result in the oscilloscope not meeting warranted performance levels at low volts per division
settings.
