The Tektronix TDS754 is a 500 MHz, 2 GS/s four-channel digital storage scope with a color screen.

Key Specifications

Analog Bandwidth 500 MHz @ 2 mV/div to 1 V/div; 450 MHz @ 1 mV/div to 1.99 mV/div
Sample rate 1 or 2 channels @ 2 GS/s, 3 or 4 channels @ 1 GS/s
Channels 4
Deflection 1 mV/div to 10 V/div with calibrated fine adjustment
Resolution 8 bit
Time Base 500 ps to 10 s/div
Record length
  • Base model – 50K samples per channel
  • 1M Option – 500K points on 1 channel; 250K points on 2 channels ; 130K points on 3 or 4 channels
  • 2M Option – 8M points on 1 channel; 4M points on 2 channels ; 2M points on 3 or 4 channels
Acquisition modes sample, envelope, average, high-resolution, peak-detect
Display Color; Zoom
Trigger modes Edge, logic, pulse; Video trigger with option 05 (NTSC, SECAM, PAL, HDTV, and FlexFormat)
Storage 1.44 Mbyte, 3.5 inch, DOS 3.3-or-later floppy disk. NVRAM storage for saving waveforms, hardcopies, and setups. Units with option HD present (requires additional hardware) have a hard disk drive

  • option 13 (RS-232 and Centronics interfaces)
  • option 2F (Extended waveform math: FFT, etc...)
  • option 1F (Floppy disk)
  • option 2C (Communication Signal Analyzer)
  • option 3C (Optical, Short Wavelength)

Internals

The TDS754C&D and TDS784C&D series are nearly identical, differences being front-panel cosmetics and the presence (754) or absence (784) of a few capacitors on the acquisition board. The only other difference is the position of instrument ID jumpers, also on the acquisition board. In fact, it is entirely possible to convert a 754 to a 784 (see above Links and the TDS784 page for more information).

Note that in the TDS700D series, the acquisition board variant is important — the CPU Board with Firmware 7.xx cannot be used together with the old acquisition board, and the CPU board with old Firmware 6.xx doesn't run with the new acquisition board. The fact that the CPU board has part number 671-4349-00 is by itself not a reliable indication of a compatible firmware version.
