Delay Generators PRL480 Specifications

The PRL-480N has been discontinued, and no new orders will be accepted. The following information is for reference only. We are working on an improved programmable delay module, and we welcome your input regarding desired features, specifications, etc.

*All measurements are made with outputs terminated into 50 Ω/-2 V, using the PRL-550NQ4X, four-channel ECL Terminators, connected to a 50 Ω input sampling oscilloscope.
Notes:
(1). The output rise and fall times are measured with both the Q and Q outputs terminated into 50 Ω/-2V. An unused complementary output must be either terminated into 50 Ω /-2 V or AC coupled into a 50 Ω load; otherwise, output waveform distortion and rise time degradation will occur. Use the PRL-504 or PRL-508, four and eight channel ECL Termination modules, respectively, for the 50 Ω/-2V termination. Use the PRL-550ND4X and PRL-550NQ4X, two and four channel ECL Terminators, respectively, for the 50 Ω/-2V termination and for connection of ECL signals to 50 Ω input oscilloscopes.
(2). fMAX is measured by AC coupling a sine wave to the D input using the differential input mode (switch up). The differential outputs are first divided by four, using the PRL-255, and then measured using the PRL-550NQ4X, four channel ECL Terminators, connected to a sampling 'scope.
