They target engineers working in semiconductor device research, power electronics and advanced materials development.
SMM3000X
Supporting pulsed current output up to ±10.5A and linear, log and pulsed sweep modes, the series functionality also includes a listing mode. This is to define custom output sequences, with minimum timing resolution down to 10μs – parameter changes can be linear, non-linear, arbitrary, or user-ordered.
Finally, the SMM3000X series provides multiple display modes: graph, roll, and measure views.
Resolution
The SMM3000X units feature 6½-digit resolution, an output capability of up to ±210V DC voltage, a ±3.03A DC current and ±10.5A pulsed current. There is programming and measurement resolution down to 10 fA /100 nV and a maximum acquisition rate of 100,000 points/s.
Telonic writes: “The SMM3000X supports four-quadrant operation, enabling simultaneous sourcing and measurement for closed-loop operations on devices under test (DUTs). It functions as a voltage source, current source, voltmeter, ammeter and ohmmeter, while also supporting pulse generation and arbitrary waveform output. This makes it an ideal platform for characterising semiconductors and other non-linear devices and materials.”
Pictured above is the Siglent SMM3311X unit (1 Channel, ±210V, ±3.03A, 31.8W, 10fA, 100nV resolution). Its price is £4,069.00-£4,882.80 including VAT).
Pulse simulation
As mentioned, in pulse mode, the SMM3000X series supports pulsed current output up to ±10.5A, with a minimum pulse width of 50μs. Telonic highlights that this allows emulation of transient operating conditions of power devices. For example, switching loss testing for GaN and SiC devices – specifically, support for R&D and validation of wide-bandgap power semiconductors.
