Descrizione
Auto Channel
Automatically selected according to the input signal frequency high or low channel channel, identifying the frequency of 60 MHz. Such as when the input signal amplitude is greater than 60 MHz shortage can not automatically select high channel, the channel should manually select high frequency measurement.
3.IF settings
Independent double-IF design, adjust the minimum frequency step of 100 Hz, frequency range 0 ~ 99.9999 MHz, can be set to increase or decrease the IF frequency mode.
4.Frequency reference
Using 5032 package 13.000MHz Warming voltage controlled crystal oscillator (VC-TCXO), frequency stability of ± 2.5 ppm.
5.Operating voltage
DC Input: DC 9V ~ 15V (with reverse polarity protection)
6.Current
Maximum 160 mA (test conditions: ① DC12V power supply; ② blue LED; ③ eight brightness)
7.Eight LED display, the highest display eight digits.
8.Eight LED brightness is adjustable, factory set to maximum brightness.
