The power button color indicates instrument power states:
•
Unlit – no AC power applied
•
Yellow – standby mode
•
Blue – powered on
4. To completely remove power from the instrument, disconnect the power cord.
Check that the instrument passes power-on self tests
Power-on self tests verify that all instrument modules are working correctly after power up.
Procedure
1. Power on the instrument and wait until the instrument screen appears.
2. Select Utility > Self Test from the top-edge Menu bar to open the Self Test configuration menu.
3. Check that the status of all power-on self tests are Passed.
If one or more power-on self tests shows Failed:
a) Power cycle the instrument.
b) Tap Utility > Self Test. If one or more power-on self tests still shows Failed, contact Tektronix Customer Support.
Connecting probes to the instrument
Probes connect the instrument to your device under test (DUT). Use a probe that best matches your signal measurement needs.

Connecting Probes
Connect TPP Series, TekVPI+, TekVPI, or other supported Tektronix analog probes by pushing them into a FlexChannel connector. The
probe base latch locks with a 'click' when the probe is fully seated.
TekVPI probes automatically set the channel input parameters for that probe (bandwidth, attenuation, termination, and so on). If a probe
has a Menu button, push that button to open an on-screen configuration menu. Follow instructions provided with active probes to set their
parameters (auto zero, degauss, and so on).
To connect a TLP058 FlexChannel Logic Probe or a TDP7700 Series TriMode™ Probe:
1. Move the locking lever to the unlocked position, then let go to reset locking lever to the center position.
2. Insert the probe into a FlexChannel connector until fully seated and the lock mechanism clicks.
