100 ns or 1 µs rise time amplifier

The TR-9600 analog signal amplifier offers a rise time of 1 µs (TR-9600-1) or 100 ns (TR-9600-2 *). The gain of the current to voltage amplifier is in ten steps for best adjustable signal to noise ratio.

10 mega sample / second ADC

A high speed analog to digital converter (ADC) digitizes the analog signal with up to a 10Msample/s sample rate for high time resolution measurements. Its 12 Bit resolution is higher than that 8Bit of typical digital oscilloscopes.

High-speed transient recorder with 100 ns sampling rate and pre-trigger function

The digital data is stored in a high-speed storage medium which is designed as transient recorder allowing a sampling rate of up to 10 Mega samples per second or one sample every 100 ns. The pre-trigger function of the transient recorder enables measurement data to be stored before the triggered event. Two million of samples can be stored in memory.

Remote operation via RS232 or IEEE488 and trigger I/O interface

The unit is capable of remote control operation via RS232 and IEEE488 interface. BNC connectors are available for trigger signal input and output or for use with external devices with TTL signal capability.

Software

Windows based software is supplied with the TR-9600 which provides all necessary functions to do remote control pulse-shape measurements and analysis via RS232 or IEEE488 interface.

Measurement Range Specifications with Light Detectors

The measurement range of the TR-9600 optometer combined with light detector is calculated by the measurement range specification of the optometer and the responsivity of the detector head as follows:

Example: Irradiance detector with typical responsivity of 3 nA/(W/cm²):

Maximal measurable irradiance (Range 0): 2 mA / 3 nA/(W/cm²) = 6,666,666 W/cm²^**
Noise equivalent irradiance (Range 9): 10 mV = 0.3 nA = 10 W/cm²
Minimal measurable irradiance (Range 0): 10 W/cm² * 50 (by user specified signal to noise ration) = 500 W/cm²

Limited Dynamic Range and Capacitance Limitation

Because of the wide bandwidth of the TR-9600 devices the noise level is higher than that of standard optometers which limits the dynamic range of the instrument. As a result TR-9600 detectors must be carefully selected according to the signal intensity to be measured.

The detector capacitance effected by the photodiode and the cable must be considered to avoid distortion of the pulse locus. To reduce these effects the recommended cable length for large size detectors for use with TR-9600 is 0.2 meters. This is even a greater concern with the TR-9600-2. Please consult the factory for technical support.

^* The TR-9600-2 with 100 ns rise amplifier limits the freedom in selecting of the light detector because of capacitance matching as well as in the available dynamic range because of increased noise level by the wide bandwidth. Please contact therefore the factory to discuss your application.

^** The maximum measurable irradiation value may also be limited by thermal radiation, intense UV radiation or other application dependent parameters which must be considered by the end-user.
