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

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.

Channel Bandwidth
Channel Bandwidth is the bandwidth over which power is measured. This is usually the bandwidth in which almost all of the power of a signal is contained.

Jitter
Jitter in technical terms is the deviation in or displacement of some aspect of the pulses in a high-frequency digital signal. Jitter is the time variation of a periodic signal in electronics and telecommunications, often in relation to a reference clock source. Jitter may be observed in characteristics such as the frequency of successive pulses, the signal amplitude, or phase of periodic signals. Jitter is a significant, and usually undesired, factor in the design of almost all communications links (e.g., USB, PCI-e, SATA, OC-48). In clock recovery applications it is called timing jitter.

Overshoot
Overshoot is the distortion that follows a major transition; the difference between the peak power point and the pulse-top amplitude computed as a percentage of the pulse-top amplitude.

Rise Time
Rise time refers to the time required for a signal to change from a specified low value to a specified high value, usually 10 and 90 percent of pulse-top amplitude (vertical display is linear power).
