Back Panel Overview
The back panel of FY8300 is as picture 1-2 below. 4 BNC terminals on the
left are DC coupling measuring terminals Trig/FSK/ASK/PSK IN, external sweep
input VCO IN, Synchronization output connector SYNC OUT, and
Synchronization input connector SYNC IN. Then follows TTL output terminal,
USB terminal, power switch and power input socket.
1. BNC connector
Trig IN: DC coupling measuring terminal.
VCO IN: Unconnected
SYNC OUT: Synchronization signal output terminal.
SYNC IN: Synchronization signal input terminal.
2. TTL signal output
⚫
Port A: The output frequency , duty cycle is the same as CH1, and the
phase is the reference phase of the instrument (constant 0).
⚫
Port B: The output frequency
, duty cycle is the same as CH1, and the
phase is CH1.
⚫
C port: The output frequency , duty cycle is the same as C2, and the
phase is CH2.
⚫
D port: The output frequency , duty cycle is the same as CH3, and the
phase is CH3.
⚫
Rx: Receive Data.
⚫
Tx: Transmit Data.
3. USB Device interface
It
’
s for communication with PC (This is a USB-TTL serial port and driver is
needed). Can programming by host computer.
4.
Power switch and Power input socket(voltage range AC100V-AC240V).
