Check that oscilloscope passes power-on self tests
Power-on self tests verify that all oscilloscope modules are working correctly after power up.
1. Power on the oscilloscope and wait until the oscilloscope 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 oscilloscope.
b. Tap Utility > Self Test. If one or more power-on self tests still shows Failed, contact Tektronix Customer Support.
Connecting Probes
Probes and cables connect the oscilloscope to your device under test (DUT). Use a probe that best matches your signal
measurement needs.
Figure 2: Connecting probes to the MSO44 or MSO46
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.
