Teardown, Repair & Experiment with an Agilent DCA 86100A Wide-Bandwidth Oscilloscope

In this episode Shahriar takes investigates the architecture and benefits of a precision sub-sampling wide-bandwidth oscilloscope. The teardown of the Agilent DCA instrument reveals a PC core combined with the acquisition board. The instrument without any plug-in modules does not perform any exciting tasks.

A 20GHz sampling module from eBay is available. However, the unit does not have an front connectors. New connectors are sourced from an old timing module and the sampling head is back to working condition. In order to test the unit, an Optellent OBP-04×10 4-channel pattern generator and error counter is used. The teardown of the unit reveals a simple design built around several transceiver ICs. The comparison between the sub-sampling scope and a real-time scope is also presented alongside measured results from the DCA.

ERASynth Micro $199 12.5MHz – 6.4GHz Portable Synthesizer Teardown, Review & Experiments

In this episode Shahriar reviews the affordable ERASynth Micro 12.5MHz – 6.4GHz portable synthesizer with a built-in LCD screen. The USB powered instrument is fully open-source, Arduino compatible and can be operated in stand-alone mode. The system block diagram and operation of the instrument is presented.

The measurements show some of the strengths and limitations of the instrument in AM/FM modulation modes and general CW use cases.

International Microwave Symposium 2019 – Industry Trade Show Overview

In this episode Shahriar presents an overview of a small portion of the vendors present on the exhibition floor at the International Microwave Symposium 2019. The IEEE MTT International Microwave Symposium (IMS) is the premier annual international meeting for technologists involved in all aspects of microwave theory and practice. It consists of a full week of events, including technical paper presentations, workshops, and tutorials, as well as numerous social events and networking opportunities. The symposium also hosts a large commercial exhibition. Co-located with IMS are the IEEE RFIC, IMBioC and ARFTG conferences.

Teardown & Experiments with Agilent mm-Wave W-Band (75 – 110GHz) T/R Module & Controller

In this episode Shahriar does a deep dive into the operation and architecture of Agilent/HP mm-Wave Extension Modules and Controller. The Agilent 85015A and W85104A work in conjunction and as the front-end for a W-Band (75-110GHz) S-Parameter T/R set. Although the mainframe system (HP 8510 Network Analyzer) is not available, a close look at the block diagrams reveals that the controller can be driven via external synthesizers to provide LO and RF signals. The detailed explanation of the entire system is presented from the ground up.

The full teardown of the mm-wave controller and T/R module are also presented and by reverse engineering the GPIB commands, the T/R module is brought to life. Several experiments show the full functionality of the system including a high-resolution CW radar demonstration.
