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.

Teardown & Repair of an Agilent 1169A 12GHz Smart Active Probe (And a Puzzle!)

Resim
In this episode Shahriar examines a failed Agilent 1169A 12GHz Smart Active Probe. The probe does not get recognized by the oscilloscope and therefore cannot be calibrated. The instrument uses an I2C interface to the probe to download the probe’s specifications and characteristics. The probe teardown reveals a simple I2C EEPROM IC. After removing the IC it becomes clear that the chip is damaged and must be replaced. A duplicate probe is used to copy the EEPROM data onto a new IC which revives the probe. With the help of the community, the CRC checksum code is discovered and the probe is assigned a new serial number.
