Ⅰ. General introduction
GDLB-601 Portable Instantaneous Signal Recorder is an instantaneous signal recorder used for kinds of industries. It is used to test the characteristics of generator such as: short circuit characteristics, No-load characteristics, excitation disturbance, De-excitation constant, and Unit load rejection records. This instantaneous signal recorder takes IPC as the core to sample and data process. It has 12.1 LCD to show, touch pad for operation, strong anti-jamming and easy operation. Ⅱ. Functions
1. Sample isolation between channels completely.
2. The instrument software has waveform zoom, data statistics, spectrum transformer and wavelet transformer tools.
3. Lots of test template to make customers finish test rapidly.
4. All the data can be exported through U-disk or wireless network.
5. Automatic upgrade interface of the tester make it easy to get latest software package and test template.
6. 12.1 LCD to show, touch pad for operation.
7. Automatically makes WORD and EXCEL test reports.  Ⅲ. Technique parameters
