Colby Instruments CPDL Series Programmable Delay Line

Features
  • Actual Measured Insertion and Return Loss Data for Different Delay Settings
  • Repeatability is 0.1 ps When Moving in the Same Direction; 0.2 ps When Moving in Either Direction
  • Repeatability is Specified at Constant Temperature

Description

The Colby Instruments CPDL (Custom Programmable Delay Line) product line does not use the trombone delay line unit, but is made entirely from precision phase matched semirigid coaxial cables and microwave coaxial relays only. For this Custom Programmable Delay Line, the customer can specify any minimum step size, but not less than 10 ps; and any delay range, but not to exceed 16 binary steps.

To compute the Number of binary Steps, multiply 3.332 x log10 x (max. delay/step size). The result needs to be rounded up to the next higher integer.

Conversely, if the step size and the number of binary steps are known, the Maximum Delay Range is computed as follows: min. step size x [ 2 exp(number of binary steps) - 1 ]. Please notice that the maximum delay range can be any number within the 16 binary steps available.

This delay line model is custom-built by specifying the Minimum Step Size and the Maximum Delay Range. Min. Step Size is 10 ps, and the max. allowable Delay Range is limited to 16 ea. binary steps. Insertion and Return Loss will depend on the length of the delay. Only precision phase matched 0.141" diameter semirigid coaxial cables are used for this unit, combined with microwave coaxial relays. Typical accuracy is 0.1%, ±5 ps.

InstraView™ Equipment Inspection



Buying used equipment doesn't always have to be a shot in the dark. We know there are plenty of differences when it comes to used equipment and quite often, choosing between different pieces is difficult, especially when the equipment is not sitting right in front of you.

Well, what if you were able to see a piece of equipment before you purchased it? Not just a picture from the manufacturer's website, but the actual piece of equipment you would receive.
With InstraView™, we move you one step closer to inspecting the equipment you're interested in without having to wait for the equipment to show up at your door.

InstraView™ works in your web browser and allows you to view the actual piece of equipment you're interested in before purchasing. You can zoom in close to see the labels with the serial number or zoom out to see the overall condition of the equipment.

It's like having the store come to you!
