The Tektronix TDS2004 is a four-channel, 60 MHz, 1 GS/s digital scope with a color LCD screen. An External trigger input on front, and the rear mounted optional TDS2MEM Communication Module provides a CompactFlash card slot, Centronics-type printer port, RS-232, and GPIB rear ports for convenient inter-connectivity.

Easy access to the MATH MENU button provides waveform adjustments (CH1-CH2, CH2-CH1, CH3-CH4, CH4-CH3, CH1+CH2, CH3+CH4) along with FFT (spectrum, harmonics, distortion, noise, impulse, vibration) measurements. Measurements can also be performed for time (frequency) and voltage (amplitude). Repetitive signals can be captured and averaged to remove noise, or captured as a single-shot signal.

Triggering of signal capturing is available through a comprehensive TRIG MENU providing Edge (rising or falling), Video (NTSC, PAL, SECAM), and Pulse Width (or Glitch) triggering on CH1, CH2, CH3, CH4, Ext and AC Line sources.
