DMM puts 7½ digits into PCI platform
By Bill Schweber -- 1/20/2005
The Signametrics SM2064 digital multimeter puts high precision into a PCI plug-in form, well-suited for test-system integrators and instrumentation users. Featuring measurement rates to 20,000 readings/sec without latency, the unit has resolution as low as 10 nV; the lowest current measurement is 50 pA.
In addition to basic voltage and current measurements, it can perform six-wire ohm readings, inductance and capacitance readings, frequency and timing measurements, and thermocouple/resistance-temperature-detection measurements. It also functions as a voltage or current source and a pulse and pattern generator.
The vendor offers front-panel-equivalent software, DLLs for Windows OS, and Linux drivers. The $2395 unit may have more functions than you need, so Signametrics offers the basic SM2064 unit, still with the same precision specifications but 1400 readings/sec, for $1595.
