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.

*This is a Web introductory price for one calibration of the TEKTRONIX 7B85. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

Available Gain
Available Gain is the ratio, at a specific frequency, of power available from the output to the power in from the source.

Decibel (dB)
A unit of measurement of power which indicates relative power. A -10 dB means a reduction in power by 10 times, -20 dB means another 10 times or 100 times overall, -30 means another 10 times or 1000 times overall and so on.

Mismatch Uncertainty
Mismatch Uncertainty is caused by re-reflections between one device (the source) and the device that follows it (the load).

Pulse Power
Pulse Power, the energy transfer rate is averaged over the pulse width. Pulse width is considered to be the time between the 50 percent risetime/falltime amplitude points. Pulse power averages out any aberrations in the pulse envelope such as overshoot or ringing.
