英文指標(biāo)：features and usage
1. the pulse signal generator - maximum pulse output voltage can reach +5v(50ω load). its repeated frequency range is se-lected by the internal oscillator frequency (1mhz-10mhz) and crystal oscillator frequency (10mhz). (1hz-10mhz to choose int mode, 10hz-10mhz to choose x-tal mode)
2. at x-tal mode, using the knob, by the 7 pre-set frequency range, you can set a frequency accuray. at the int mode, you can set a stochastic repeated frequency.
3. it can generate a pulse wave of high quality (1hz-10mhz),thus it has a very wide application in all kinds of circuit test. in the analyzing and design of a digital circuit, it can be used as a clock pulse source.
