TEKTRONIX 7B85 Horizontal Time Base Plug-in

Tektronix 7B85 Horizontal time base recommended for use with 7000, 7800 and 7900 Series Mainframes to provide optimum bandwidth/ sweep-speed compatibility. Features: Delta Time Measurements with Crt Readout. Delay Time Measurements with Crt Readout. Vertical Trace Separation between Two Delayed Sweeps. 1 ns/div to 5 s/div Calibrated Time Bases. Triggering to 400 MHz. Variable Trigger Holdoff. Peak-to-Peak Auto Triggering. Sweep Rates - 5 s/div to 10 ns/div in 27 steps (1-2-5 sequence). 10X MAGNIFIER extends fastest calibrated sweep rate to 1 ns div. The uncalibrated VARIABLE is continuous to at least 2.5 times the calibrated sweep. Trace Separation Range - Funclional only in Delta Delay Time mode when alternating or chopping between time-base units. The second delayed sweep display can be vertically positioned at least 3 div below the first delayed sweep display. Delay Time Range - 0.2 or less to at least 9.0 times TIME/ DIV setting. Jitter - 0.02% of TIME/DIV setting + 0.1 ns, or less. External Trigger Input - Max input voltage is 250 V (dc + peak ac) Input R and C is 1 M-Ohm within 5% and 20 pF within 10%. The level range (excluding p-p AUTO) is at least ± 1.5 V in EXT + 1, and at least ±15 V in EXT + 10.

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.
