The OP8214 peak detector provides an interface to measure the amplitude for up to 4 pulses. This panel provides both SMA and BNC connectors. The OP8214 requires external power input.
|SMA Connector||The SMA connector is used to connect the input signal. When the OP8214 detects a high-speed pulse in this input signal, it conditions it by stretching it to the extent that the OP5340 Analog-In can read and process the pulse.|
|Status LED||Blinks to indicate each high-speed pulse.|
|BNC Connector||Used to connect the OP8214 to an external monitoring device (i.e. an oscilloscope) to view the signal sent to the simulator.|

Peak Detector Specifications
Input Analog Pulse
0 to 3.5 volts
Pulse width minimum/ maximum
10 to 50 nanoseconds
50 millivolts - smaller pulses will be ignored
Output Analog Level
Differential (compatible with OPAL-RT ADC mezzanine)
0 to 4 volts, differential signals or single-ended follower
Hold time for peak value
± 20 microseconds. FPGA uses the ready_to_read signal to read (see timing diagram)
DB37, female, supports the 4 analog differential pair
Output Digital Signal
± 20 microseconds. When high, during around 20 microseconds, it means that the output analog value can be captured by the ADC mezzanine.
DB37, female, supports the 4 digital signals
When an analog pulse is detected (above 50 mv), the LED is activated.
