Tektronix SD-14 3GHz Sampling Module

The Tektronix SD-14 is a dual-channel sampling module that extends oscilloscope capabilities for high-speed signal acquisition up to 3 GHz. Engineered for signal integrity analysis, high-speed data communications, and characterization of logic families and analog circuits, the SD-14 delivers precise measurements with minimal loading effects through its high input impedance and low input capacitance.

– Technical Specifications

• Bandwidth: 3 GHz (typical)
• Channels: Dual channel
• Rise Time: 140 ps (10% to 90%)
• Input Impedance: 100 kilohm with 0.5 pF capacitance
• Dynamic Range: 7 Vp-p within ±3.5 V offset range
• Maximum Input Voltage: ±15 V
• Displayed Noise: 7 mV (typical, unity dot response)
• Record Length: 1 Mpoint
• Time Coincidence Between Channels: 10 ps accuracy; <0.2 ps/°C stability
• Probe Cable Length: 1 meter

– Key Features

The SD-14 exhibits controlled transient response with specification across four time windows following a step input: <1.5 ns (+12%, −25%), 1.5 to 4 ns (+1%, −3%), 4 to 30 ns (±2%), and elsewhere (±1%). Dot transient response maintains ±5% accuracy after calibration at operating temperature for signals up to 0.5 Vp-p and adjusts to unity for signals up to 1.0 Vp-p. The high input impedance of 100 kilohm minimizes circuit loading, critical for non-invasive probing of sensitive circuits.

– Typical Applications

The module suits high-speed digital characterization, optical design measurements, electrical design verification, and signal integrity analysis on circuits with logic families ranging from standard to advanced nodes. Its 3 GHz bandwidth and 140 ps rise time enable capture of transient phenomena in modern switching circuits.

– Compatibility & Integration

The SD-14 operates with 11800-series scopes, CSA803 and 11800 series oscilloscopes, 11801A, 11801B, 11801C mainframes, and CSA803C/11801C sampling oscilloscopes. Physical dimensions are 8 × 6 × 4 inches with a weight of 5 lbs.
