Gigahertz-Optik’s hand-held P-9710-4 radiometer/photometer now features an external TTL trigger input function useful for remote timing of pulsed light measurements. In the P-9710-4 pulse energy mode, the measurement begins automatically upon trigger input.

The P-9710-4 is capable of measuring the pulse energy (joules, J/cm², lux-seconds, effective candela) of single- and multiple-burst pulsed events >1 microsecond in length. Stepped auto-ranging allows the user to zoom-in on the correct gain level with the last setting stored for future use. Independent of signal magnitude, system bandwidth is 0.166 Hz (at 6s) to > 300 MHz within the unit’s current measurement range of 0.1 pA to 2 mA.
