The DCA Pro is an advanced new design that features a graphics display, USB communications, PC Software and an enhanced component identification library.
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 pin-out and also measure a range of component parameters such as transistor gain, leakage, MOSFET and IGBT threshold voltages, pn characteristics and much more.
The DCA Pro supports all the components that the popular Peak Atlas DCA55 supports, but adds plenty more.
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 1uA) and approx transconductance (for span of 3mA-5mA)
Q. Would this product be able to be used to grade LED's using the VF measurement to work out its luminosity? Basically does the VF value give you a guide to brightness so you can select LED's for a display arrays?
If it can how does it work?
A. Hi Scott, thanks for your question. This will test the VF on an LED and normally the lower VF will usually indicate the brightness. It will help you identify different ranges.
