TEKTRONIX 11A81 Single Channel High-bandwidth Presampler Plug-in

Single channel, high-bandwidth, presampler plug-in designed specifically for the 11403A Digitizing Oscilloscope and the CSA 404 Communications Signal Analyzer. Characteristics: Bandwidth - 3 GHz typical (calculated from rise time using the formula BW = 0.38/t,). Risetime - <= 130 ps. Deflection Factor -10 mV to 1 V/div in 1-2-5 sequence. Accuracy - delta.V: ±(1.0 + 0.01 div.); Offset: ±(0.6% + 0.01 div. ); DC Balance: ±0.1 div. Offset Range - ±50 divisions. Resolution: Coarse - 0.25 div; Fine - 0.025 div. Overdrive Recovery - At 10 and 20 mV/div: to within ±(2.0% +0.1 div) within 10 ns from ± 1 V step. Typical Displayed Noise (RMS) - 0.025 div from 10 mV/div to 1 V/div. Input Impedance - 50 ohm ± 1. 0%; VSWR <= 1.45:1 at 10 mV/div, DC to 2 GHz; VSWR <= 1.25:1 at 20 mV/div to 1 V/div, DC to 2 GHz. Disconnect Threshold - DC signal: ±(6 V ± 1 V); AC signal: 5 Vrms typical (DC to 100 MHz). Input Coupling Modes - DC and OFF. Maximum Input Voltage - 5 Vrms (0 .5 W) or 0.25 watt-second pulses not exceeding 25 V peak. External Trigger - Range: ± 1 V. Resolution: Fine: ±2 mV/step; Coarse: ±20 mV/step. Accuracy: ±5% of trigger level range. Sensitivity: 40 mV p-p from DC to 200 MHz; increasing to 150 mV p-p at 800 MHz; increasing to 200 mV p-p at 2 GHz. Maximum Safe Input level: ± 1 V. Internal Trigger - Sensitivity: 2.0 div p-p from DC to 625 MHz, typically increasing to 4.5 div p-p at 1 GHz

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.
