Ultra-fast Pulse Generator for TCSPC (100ps, +/- 5V)
NPG-1H20A is an ultra-fast pulse generator especially for driving M-Z modulator. It has precision pulse width and pulse height control and it can accept any logic level as trigger input. The pulse width can be set to lock or tuning mode by pressing the knob, while entering the lock mode, the last setting will be saved for power-cycling convenience. The pulse height can also be changed by another knob, while it has additional coarse tuning mode for faster adjustment.
Compared to previous model, NPG-1H20A integrates a high-performance temperature control system for its RF gain block, therefore the output pulse stability of height and width is greatly improved, that is resistant to ambient temperature changes and it can run stably for a long time.
- Minimal 100ps pulse width
- Any-level trigger input
- Pulse height and pulse lock/tuning mode with LED indication
- Integrated RF gain block temperature control
- USB communication control port
Applications
- Narrow pulse generation
- IM-based chopper laser
- Electro-optical intensity modulation
- Optical telecommunication
- RF test instrumentation
2ns pulse width @100MHz, 10V amplitude
Product specifications and Brochures
Product Brochure Link:
Note:
The maximum pulse width may be limited by the input pulse width.
The maximum pulse amplitude is tested @ 100MHz trigger input and 200ps pulse width.
The power consumption may up to 35 watts within a few seconds while power-on, because the module TEC is achieving the target temperature.
Power Supply - Users should use a high quality 12V DC power supply with at least 3A current rating. Either the attached AC-power adaptor or a high-quality linear power supply is recommended.
Pulse Width Control – Users may press the knob to toggle between lock/unlock mode for pulse width control. The pulse width can be adjusted by turning the knob in unlock mode, while pulse width can be fixed and stored by pressing the knob into lock mode. Each time power cycling, pre-stored pulse width will be loaded automatically with lock mode on.
Pulse height control – Users may press the knob to toggle among lock/coarse-tuning/fine-tuning mode for pulse height control. The last tuned pulse height can be fixed and stored by pressing the knob back into lock mode. Each time power cycling, pre-stored pulse height will be loaded automatically.
Trigger threshold adjustment - The threshold is pre-set to 0V by factory default. The LED of TRIG‘D is steady off when trigger is not present or not properly triggered. Adjusting the trigger threshold with a screw driver till the LED turns blinking, if needed.
LED indicators
Temp. Control Debug Port – for factory use only.
USB Communication Port – Users can set the pulse width and height by connecting this port to a computer via a USB type-B cable. The protocol is based on a series of simple four-byte UART commands as follows
