TEKTRONIX 7904 Oscilloscope Mainframe

Tektronix 7904 500 MHz Oscilloscope Mainframe. VERTICAL SYSTEM; Channels: Two left-hand plug- in compartments: compatible with all 7000-Series Plug·ins. Bandwidth determined by mainframe and plug-in unit. Modes of Operation: LEFT , ALT , ADD. CHOP. RIGHT. Chopped Mode: Repetition rate is approx 1 MHz. Trace Seperation Range (Dual-sweep Modes): The B trace can be positioned 4 divisions above or below the A trace. Delay Line: Permits viewing leading edge of displayed waveform when using 7880 and 7890 Series Time Bases. 7850 Series not recommended. HORIZONTAL SYSTEM; Channels: Two right-hand plug-in compartments; compatible with time bases of the 7880 and 7890 Series. 7000-Series vertical amplifiers and specialized plug-ins may also be used. Fastest Calibrated Sweep Rate: 500 ps/div with the 7892A. Chopped Mode: Repetition rate is approx 200 kHz. X-Y Mode: Phase shift is within 2° from dc to 35 kHz without phase correction (dc to 1 MHz with phase correction. Option 02) between vertical and horizontal channels. Bandwidth is dc to at least 1 MHz. CRT: Internal 8 x 10 cm graticule with variable illumination.

Averaging
Averaging is a mathematical process to reduce the variation in a measurement by summing the data points from multiple measurements and dividing by the number of points summed.

Fall Time
Fall time is the time required for the amplitude of a pulse to decrease (fall) from a specified value (usually 90 percent of the peak value exclusive of overshoot or undershoot) to another specified value (usually 10 percent of the maximum value exclusive of overshoot or undershoot).

Noise Density
Noise Density is the amount of noise within a defined bandwidth, usually normalized to 1 Hz.

Resolution Bandwidth (RBW)
Resolution Bandwidth (RBW) is the minimum bandwidth over which you can separate two signals and still see them.
