Provisional entry — research in progress
This page was generated automatically from cited public sources and hasn't completed the full research pass yet. Every specification shown carries its source; more detail is added as research completes.
The TDS 540 is a 500 MHz, 1 GS/s quad-channel digital oscilloscope. The TDS 540 features four full-featured channels and an eight-bit digitizer. The TDS 540 includes GPIB standard programmability and supports up to 50,000-point record length with optional memory.[1][2]
What it is
The TDS 540 offers a maximum analog bandwidth of 500 MHz and a maximum digitizing rate of 1 gigasample per second (GS/s) when using a single channel.[1][2]
The TDS 540 provides four full-featured acquisition channels and uses eight-bit digitizers.[2]
The instrument was introduced in 1992 and was produced by Tektronix.[1][2]
How it works
The TDS 540 includes multiple acquisition modes: Sample, Envelope (min/max values over acquisitions), Average (selectable from 2 to 10000), and Hi-Res mode which improves vertical resolution on low-frequency signals.[4]
The instrument supports four channels with independent vertical scales and an eight-bit vertical resolution, with DC gain accuracy of ±1.0%.[4][2]
The TDS 540 features waveform math functions such as invert, add, subtract, and multiply two waveforms, and with the optional option 2F, integrate, differentiate, or perform an FFT.[2]
Applications
The TDS 540 provides 22 automatic waveform measurements, including time interval, glitch detection, runt, pattern, state, and TV triggering.[4]
The instrument can display X-Y plots and offers infinite and variable persistence display modes (250 ms to 10 s) with gray scaling for intensity information.[4]
Why won't it start?
Documented failure modes, common issues, and field considerations.
- A common failure reason on early TDS-family scopes are surface-mounted capacitors leaking corrosive electrolyte.
