High-precision Delay Generator (RS232 Command Control) for Computer and Single Chip Microcomputer

Features:
1. All settings are completed by RS232 control command, and all setting parameters can be queried by RS232 control command;
2. Two communication interfaces: mini-B USB interface and RS232 interface can be used to power the delayer. The Mini-USB interface can provide virtual serial communication, and users can connect the delayer through this interface with the computer. The RS232 interface provides standard serial communication, and its TX and RX pins are 3.3V TTL signal level. Users can connect and control through logic circuits such as single-chip microcomputer, DSP, FPGA and for ARM. Users can also use the USB-RS232 TTL chip or adapter to connect and control with a computer.
3. All control and query commands are described in detail in the accompanying instructions;
4. Computer control software and BCB language source code are included. And there are corresponding RS232 commands next to each command in the software for users' reference, which is convenient for users to quickly develop or integrate into their devices;
5. This module has 4 TTL signal output channels, 1 RF output channel, 2 RF input channels and 1 TTL input channel;
6. Four TTL output channels: the frequency of each channel can be adjusted from 1Hz to 1MHz respectively (when triggered internally). And the trigger signal can be divided separately when triggered externally. The duty cycle of the output signal of each channel is adjustable;
7. Four TTL output channels: the signal delay of Ch1 and Ch2 channels is adjustable from 0ns to 1ms (the minimum resolution is 0.25ns), and the signal delay of Ch3 and Ch4 channels is adjustable from 0 to 10S (the minimum resolution is 0.1us);
8. Four TTL output channels: the high-level width of Ch1 and Ch2 channels is adjustable in the range of 15ns-99us, and the minimum step length is 0.25ns. And the high-level width of Ch3 and Ch4 is adjustable in the range of 0.1us-999ms, and the minimum adjustable step size is 0.1us;
9. Four TTL output channels: the output is a standard TTL signal, the high level is 5V, the output impedance is 50 ohms or 1M ohm self-adaptive. The output signal of each channel can be inverted level output, or the output is pure high level or 0V low level;
10. If the pulse signals output by the four channels have the same frequency or are integer multiples (e.g., between 1kHz and 3kHz), the pulses will be automatically synchronized (the time jitter between them is less than 50ps).
11. When it is externally triggered, the time jitter of the pulse output from the four channels with a delay relative to the trigger pulse will vary depending on the selected RF signal, with a minimum of 2.5ns. If the RF selects the 76Mhz signal of a laser oscillator, the jitter will be about 13ns. The pulse signal of the four-channel delay output is fully synchronized with the selected RF signal (time jitter is less than 50ps).
12. The signal generator also has a counting function, which can count the RF in the range of 100Hz~250MHz, accurate to the hundred position. TTL signals can also be counted from 1 Hz to 1 MHz.
13. The signal generator can divide the selected RF signal in the range of 1~255.
                          
Application:
- This module supports high-precision level width adjustment. It is particularly suitable for acousto-optic or electro-optical control of ultra-short femtosecond or picosecond laser pulses;
- This module can be used for synchronous control between pulsed lasers such as Q-switched lasers;
- This module can delay the laser pulse signal and trigger other instruments.
