In this episode Shahriar repairs an Agilent 33250A function and arbitrary waveform generator which does not power on. The unit is equipped with a soft power switch which might be responsible for the fault. After a brief look at the unit’s constructions, the fault is traced to a few possible locations.

The schematic of the soft power circuitry is presented and the internal switching power supply is closely examined. After the fault is located, the repair is presented. The block diagram and operation of a current mode DC-DC switching IC is also presented.

In this episode Shahriar reviews the new Keithley 2450 Source Measure Unit (SMU). This model, which is the successor to the widely adopted Keithley 2400, offers performance improvements as well as a brand new interface platform with multi-point touch screen.

The review demonstrated the instruments GUI, scripting capabilities through the TSP interface and various performance parameters. Furthermore the scripting features are used to measure super capacitor capacity, the performance of a wireless charging system, characterization of optoelectronic components and semiconductor elements.
