3. Check the version of the latest available firmware at the tek.com/software. Enter the model number of your oscilloscope in the search
box and search for the firmware.
If the firmware version on the web is newer than what is currently installed, update your instrument firmware.
4. Install the firmware on embedded OS instruments.
a) Download the latest firmware and unzip the files on your PC.
b) Copy the designated firmware file into the root folder of a USB flash drive.
c) Insert the USB flash drive into a USB port on your oscilloscope. The instrument automatically recognizes the firmware install file
and starts the installation process.
d) Follow any on-screen instructions. The oscilloscope take about 10 minutes to install the new firmware.
Do not remove the USB flash drive or power off the instrument during this time.
e) After the oscilloscope displays a message that it has completed the upgrade, the scope will reboot automatically.
What to do next
To confirm the firmware update, locate the version number found in the About window under the Help menu. Confirm that the instrument
firmware version number matches the firmware version number that you just installed.
Run Signal Path Compensation (SPC)
Run SPC when you first receive an instrument, and 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 per
division or less.
About this task
To access the user interface on a Low Profile instrument, connect a monitor to a video port on the rear of the instrument, and connect a
mouse to any USB Host port. You do not need to connect a mouse if your remote monitor is touch-capable. You can also remotely access
the user interface of a network-connected instrument by entering the instrument's IP address in a web browser.
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 instrument not meeting warranted performance levels at
low volts per division settings.
Before you begin
Disconnect all probes and cables from the front-panel channel inputs and rear-panel signal connectors.
Procedure
1. Power on and warm up the instrument for at least 20 minutes.
2. Tap Utility > Calibration.
3. Tap Run SPC. The SPC Status readout shows Running while SPC is running. SPC can take three minutes approximately per channel
to run, so wait until the SPC Status message changes to Pass before reconnecting probes or cables and using the instrument.
CAUTION: You can abort the SPC calibration by tapping Abort SPC. This may leave some channels uncompensated,
resulting in possible inaccurate measurements. If you do abort the SPC, make sure to run the SPC procedure completely
before using the instrument to take measurements.
4. Close the Calibration configuration dialog when SPC has completed.
If the SPC fails, write down any error message text. Make sure that all probes and cables are disconnected and run the SPC again. If
the SPC still fails, contact Tektronix Customer Support.
