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


General description of the used TEKTRONIX 11A81 for sale.
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
