Tektronix TDS3044B Digital Phosphor Oscilloscope
The TDS3044B oscilloscopes developed by Tektronix come standard with NTSC, PAL, and SECAM (all fields or all lines) triggering capacities. The TDS3VID application module expands this essential video triggering by including the accompanying highlights: a Video QuickMenu function that enables you to show a base and side menu that contains video capacities valuable for showing and measuring broadcast standard waveforms, including trigger source, when to trigger, and video Autoset. The Autoset function consequently changes the vertical, horizontal, and video trigger settings to show a video waveform triggered on all lines and fields. Then, the user can physically alter controls to upgrade the display. This capacity is accessible in the Video QuickMenu and in the Acquire menu.
The TDS3044B Digital Phosphor Oscilloscope also includes a custom video function that enables the user to determine custom horizontal scan rates with a specific end goal to trigger on non-broadcast video waveforms, such as those utilized by PC screens and medical equipment. The TDS3044B offers simple HDTV Features; the TDS3VID and TDS3SDI modules enable the user to work with rising simple HDTV principles. Trigger on a scope of HDTV groups – 1080i, 1080p, 720p, and 480p. Additionally, it uses the vectorscope on simple HDTV with graticules for both 100 and 75% shading bars. It is important to see a solitary line of the video waveform. For instance, the programming data in the NTSC signal in some cases is found on Line 20. Line Count triggering enables the user to trigger on a specific line by looking through the line numbers and choosing the one they need.

How-to Troubleshoot the TDS304B Tektronix TDS3000B Oscilloscope
General Troubleshooting Tips
- Verify that your factory defaults were in fact recalled before configuring your scope or taking any measurements.
- Double check the circuit configuration. An incorrect connection or missing wire could alter your results.
Function Check procedure for Tektronix Oscilloscope
- Connect your oscilloscope power cable
- Power on your oscilloscope. Confirm that self tests have passed.
- Connect your oscilloscope probe to channel 1. Connect the probe tip & reference lead to PROBE COMP connectors.
- Press the AUTOSET button. You should see a square wave in the display (approx. 5V at 1kHz).
Troubleshoot: RS-232 Communications Port
- Verify the correct cable and adapters are in use
- Verify that cables are connected to the correct ports
- Reset the RS-232 parameters to Defaults, then set the Baud Rate to match the computer or hard copy device.
- Enable the debug window to view the RS-232 status, data transmitted, data transceived, and errors.
Troubleshoot: No signals onscreen (after scaling & offsetting)
- Double check for loose wiring or connections from the probe alligator clips / grabber clips.
- Verify your black leads from the probes are grounded.
- If earth ground is present, verify black leads of the probes and earth ground are at the same potential.
Troubleshoot: Unexpected signal onscreen
- Double check the timescale, a small piece of a larger waveform might be displayed.
- Double check that probe clips are connected to the correct circuit node.
If your problem persists
- Recall factory defaults once more and try again
- Contact Tech Support for further assistance
