f.
When the firmware install is finished, remove the USB drive and restart the instrument.
NOTE. Do not power off the instrument, or remove the USB flash drive if installing from the drive, until the instrument
finishes installing the firmware. The instrument displays a message when it is OK to power off.
4.
To confirm that the firmware was updated:
a.
Tap Help > About in the Menu bar.
b.
Check that the firmware version number listed on the screen is the same version that you downloaded.
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.
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.
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 several minutes per channel
to run, so wait until the SPC Status message changes to Pass before 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.
5.
If the SPC fails, write down any error message text. Make sure that all probes and cables are disconnected (except for the
LPD64) and run the SPC again. If the SPC still fails, contact Tektronix Customer Support.
Connect to a network (LAN)
Connecting to a network allows you to remotely access the instrument.
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.
Work with your network administrator to obtain the required information to connect to your network (IP address, Gateway IP
address, Subnet Mask, DNS IP address, and so on).
1.
Connect a CAT5 cable from the instrument LAN connector to your network.
2.
Select Utility > I/O on the menu bar to open the I/O configuration menu.
