Colby PDL-30A Programmable Delay Line

The Colby Instruments PDL-30A is a programmable delay line designed for precise signal timing adjustments in advanced electronic applications. It has a wide delay range and high resolution, enabling integration into automated test and measurement systems where accurate control of signal paths is critical. The device utilizes Colby Instruments' patented electromechanical trombone technology, combined with precision-cut semi-rigid coaxial cable and aerospace-grade microwave relays, to achieve its performance.

Technical Specifications Delay Range and Resolution: * Standard Total Delay Range: Up to 10 ns.

• Binary Delay Extensions: Typically includes 625 ps, 1.25 ns, 2.5 ns, and 5 ns.
• Step Size (Standard): 1 ps.
• Step Size (High-Resolution Option): 0.5 ps (Factor 2 higher resolution).
• Dual Matched Delay Lines: Each can provide a delay range of 312.5 ps.
• Trombone Unit: Integrated within the PDL-30A, it has a maximum settling time of 1 second. The unit can be configured to provide identical performance to the PDL-10A for bandwidths up to 18 GHz by removing a specific semi-rigid cable.
• Customizable Ranges: The PDL-30A series can be ordered with different total delay ranges, either less than or greater than the standard 10 ns. Electrical Characteristics: * Frequency Range: DC to 18 GHz. The insertion loss is specified as -3dB at 13 GHz, extending to 18 GHz.
• Insertion Loss: Typically -3dB for 13 to 18 GHz. Actual measured insertion loss data for various delay settings is provided with each unit.
• Return Loss: Not explicitly detailed for the PDL-30A, but typically ranges from 18 dB to 2 GHz and 10 dB to 8 GHz for other Colby delay lines.
• Power Handling: 10W CW, 50W peak.
• Accuracy: Absolute accuracy is typically ±0.2 ps.
• Repeatability: Typically 0.1 ps. Repeatability is specified at constant temperature.
• Delay at 0 ns Setting: 3.30 ns.
• Line Voltage: Selectable for 85-102 V, 110-122 V, or 215-245V at 50/60 Hz.
• Power Requirement: 120 VA.
• Operating Temperature Range: Recommended range is 10ºC to 30ºC. Interfaces: * Programmable Interface: Supports remote delay setting via GPIB (IEEE 488.2) protocol, allowing for simple commands to realize specific delays. This interface ensures instrument repeatability, accuracy, and performance.
• Manual Control: Requires the MT-1A Microterminal for manual control of delay settings.
• Connectors: Features SMA connectors. Specific configurations may utilize connectors 2 and 3 for direct access to the Trombone Unit. Physical Characteristics: * Dimensions: 13 3/8" Long x 12 7/8" Wide x 5 1/4" High.
• Weight: Approximately 16.1 lbs.
• Rackmount Option: A 19" rackmount option (RMO) is available. Compatibility: * Microterminal: Requires the MT-1A Microterminal for manual operation.
• GPIB (IEEE 488.2): Supported for remote programmability.
