Multifunctional Level Variation Recorder
New
DLR-203
A level variation recorder capable of recording voltage variations on the same time axis as when recording signal level variations.
By simultaneously recording the level meter input 2 channels and the voltmeter input 2 channels, it is effective for failure analysis of communication lines. Diverse trigger function does not overlook the cause of failure.
Equipment Category
Measuring instruments for transmission characteristics
Power supply
AC adaptor
It incorporates two channels for recording signal level variations and another two channels for voltage variations.
Equipped with various trigger functions, DLR-203 securely detects all failure causes.
Capable of remote control through IP lines.
Measurement data can be saved in USB memory.
It is possible to operate it with a personal computer, a tablet, etc. by remote desktop.
