Keysight / Agilent 3784A Digital Transmission Analyzer

  • G.821 Error Analysis at 704 kb/s, 2, 8, and 34 Mb/s
  • Optional Jitter at 2, 8, and 34 Mb/s
  • Clock Synthesizer From 1 kb/s to 50 Mb/s


The Agilent / HP 3784A is a BER and jitter test set for manufacturing, commissioning, and maintaining network equipment operating at CEPT telecom interface rates of 704 kb/s, 2, 8, and 34 Mb/s. It has a clock synthesizer and TTL/ECL interfaces for general-purpose BER testing at any rate between 1 kb/s and 50 Mb/s and has optional jitter or 64 kb/s codirectional interfaces.

For network operators, the Agilent / HP 3784A performs error performance analysis during the installation and maintenance of digital transmission networks and monitors in-service error performance using line code error detection. Long-term measurements can be made unattended and the results logged to an external printer. Several ease-of-use features include measurement presets, automatic receiver set-up and pass/fail thresholds.

For digital equipment manufacturers, the Agilent / HP 3784A synthesized clock source and binary interfaces allow general-purpose error performance testing of any design that transports or stores digital data. For production test, the Agilent / HP 3784A can be rack-mounted and automated with HP-IB or RS-232-C remote control.

For manufacturers of telecommunications equipment, the Agilent / HP provides a wide range of test patterns and enables flexible frequency offset tests and testing at non-standard rates. The Agilent / HP 3784A provides fully automated jitter tolerance and transfer function measurements. The jitter analysis facility enables the correlation of jitter hits with error bursts. Through-data jitter modulation allows jitter to be added to a fully-framed test signal passing through the Agilent / HP 3784A for jitter tolerance testing of demultiplexers. The Agilent / HP 3784A with Option 002 can be paired with the Agilent / HP 3764A Digital Transmission Analyzer with Option 002 or 007 to provide complete error and jitter test capability for manufacturing applications up to 139 Mb/s.

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!
