The DCA Pro is an advanced new design that features a graphics display, USB communications, PC Software and an enhanced component identification library.
- Automatic component type identification.
- Automatic pinout identification (connect any way round).
- The DCA Pro supports all the components that the popular Peak Atlas DCA55 supports, but adds plenty more. Components supported include:
- Transistors (including Darlingtons), Silicon and Germanium types. Measures gain, Vbe and leakage.
- MOSFETs, enhancement mode and depletion mode types. Measure on-threshold (at 5mA) and approx transconductance (for span of 3mA-5mA).
- JFETs, including normally off SiC types. Measures pinch-off voltage (at 5uA) and approx transconductance (for span of 3mA-5mA).
- IGBTs (insulated gate bipolar transistors). Measures on-threshold (at 5mA).
- Diodes and Diode networks.
- LEDs and bicolour LEDs (2 lead and 3 lead types).
- Zener Diodes with measurement of zener voltage up to 9V at 5mA.
- Voltage regulators (measures regulation voltage, drop-out voltage, quiescent current).
- Triacs and Thyristors that require less than 10mA of gate current and holding current.
Stand-alone or with a PC
The instrument can be used stand-alone or connected to a PC. Either way, the DCA Pro will automatically identify the component type, identify the pinout and also measure a range of component parameters such as transistor gain, leakage, MOSFET and IGBT threshold voltages, pn characteristics and much more.
When connected to a PC using the supplied USB cable, a range of low current curve-tracing functions can be performed. Various graph types are available, with more to follow:
- Bipolar transistor output characteristics, IC vs VCE.
- Bipolar transistor gain characteristics, hFE vs VCE.
- Bipolar transistor gain characteristics, hFE vs IC.
- MOSFET and IGBT output function, ID vs VDS.
- MOSFET and IGBT transfer function, ID vs VGS.
- JFET output function, ID vs VDS.
- JFET transfer function, ID vs VGS.
- Voltage regulator, VOUT vs VIN.
- Voltage regulator, IQ vs VIN.
- PN junction I/V curves, forward and reverse options (for Zener diodes).
Curve tracing is performed using test parameters in the range of +/-12V or +/-12mA. All curve-tracing data can be instantly pasted into Excel© for further graphing and analysis. PC Software is included with the DCA Pro on a Peak USB memory stick. Software designed for Windows XP, Vista, Windows 7 and Windows 8 (all 32 or 64 bit).
