TDS 6804 B Digital Oscilloscope

The Tektronix TDS 6804 B is a four-channel digital storage oscilloscope (DSO) belonging to the TDS6000B/C series. The TDS 6804 B provides an 8 GHz bandwidth and a real-time sample rate of 20 GS/s on all four channels simultaneously. The instrument includes a dual-processor architecture and runs the Microsoft Windows XP operating system.^[1][2][4]

The TDS 6804 B uses a real-time sampling architecture. On all four channels the oscilloscope samples at 20 GS/s with an interpolated time resolution of 500 fs per sample point. The instrument incorporates a dual-processor system consisting of a 2.8 GHz Pentium 4 and a 583 MHz PowerPC to handle acquisition, processing, and display tasks. The user can select digital signal processing (DSP) filters on each channel to correct magnitude and phase response or disable DSP to use the full true analog bandwidth.^[4]

The oscilloscope provides Pinpoint triggering with over 1400 combinations, including serial pattern triggering up to 3.125 Gb/s with 8b/10b protocol decoding (on models with Option ST or PTD). The MyScope custom control windows allow users to create personalized interfaces. Record length on all four channels is up to 32 Msamples, extendable with optional upgrades.^[4]

The TDS 6804 B is applied in signal integrity analysis, jitter and timing characterization, validation and debug of next-generation digital designs, and compliance testing of high-speed serial data standards. The instrument is also used in computer, datacom, and storage area network equipment design, as well as in high-energy physics data acquisition. Optional software extends the oscilloscope for extended video mask testing and jitter analysis.^[1][4]
