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

*This is a Web introductory price for one calibration of the TEKTRONIX 11A81. 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.

Crest Factor
Crest factor or peak-to-average ratio (PAR) is a measurement of a waveform, calculated from the peak amplitude of the waveform divided by the RMS value of the waveform

Linearity
Linearity is the relative difference between the displayed power ratio, Dx/D0, and the actual (true) power ratio Px/P0 caused by changing the displayed power level from the reference level, D0, to an arbitrary displayed level, Dx.

Phase Noise
Phase noise is the frequency domain representation of rapid, short-term, random fluctuations in the phase of a waveform, caused by time domain instabilities. Phase noise (L(f)) is typically expressed in units of dBc/Hz, representing the noise power relative to the carrier contained in a 1 Hz bandwidth centered at a certain offsets from the carrier.

Sensitivity
Sensitivity is the minimum magnitude of input signal required to produce a specified output signal having a specified signal-to-noise ratio, or other specified criteria.
