CR7133A standard time slot generator is a testing device used to verify the accuracy of on/off timing instruments and pulse timing instruments. The testing principle is to use a signal generator to output standard signals with accurate time intervals and sequence, replacing the on/off signals or pulse signals at the test site. By comparing the difference between the data measured by the time measuring instrument and the actual time signal sequence emitted by the signal generator, the purpose of determining whether the time measuring instrument is accurate and reliable can be achieved.

The signal generator adopts a high-precision quartz crystal oscillator source and FPGA, with precise output time base; The interval time of the output sequence signal can be set arbitrarily between 100ns and 999.9ms; Output as OC (open collector) on/off signal or pulse signal.

The instrument is designed as a portable structure that can be easily brought to any site for use. The signal generator is easy to operate and clear at a glance. No specialized training required, ready to use, testing work can be completed with just one click.
