The certificate number SourceMeter (digital source table) series is designed for those requiring close
combination of
excitation sources and measurement functions, requiring precise voltage sources and measuring current and
voltage simul
taneously.
Designed for testing applications. All source tables are powered by a precision, low noise, high
stability DC
power supply with a read function and a low noise, high repeatability and high b impedance.
The 5 half
multi function
table is composed of compact single channel DC beter tester. Its function is equivalent to the
synthesis of voltage
source, current source, voltmeter, ammeter and resistance meter. through
The manufacturers of components
and modules in
the letter, semiconductor, computer, automotive and medical industries will find that the source meter
instrument is of
great practical value for various characteristics analysis and production process testing.
The 2420 type
high voltage
source has a table power of 60W, which can provide and measure the voltage from + 5 V (source) and + 1 (V)
to + 60V, and
the current from + 100pA to + 3A. 2420
Production testing applications include resistance and resistance
networks, ther
mistors, solar cells, ordinary batteries, large current, or medium power diodes that must be tested under
high current
conditions
(including switches and Schottky diodes). 2420 is also suitable for IDDQ testing of CMOS
integrated circuits
to monitor current consumption of battery powered medical devices such as generators.
