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.
