• GS-USB-PRO-HI

USB Spectrometer for Proportional Counters and neutron detectors

This is a standard GS-USB-PRO with high impedance coupling, making it suitable for gas proportional counters and some neutron detectors. 
The only difference between the GS-USB-PRO is the internal HV coupling which has 10 Mega ohm load resistor and 50 pF capacitor coupling.





Works with Free software and simply connects it to any PC or Mac* USB port and works with any brand of scintillation detector for spectrometry or any geiger counter for simple counting experiments. 

NEW FEATURES AND IMPROVEMENTS

Inbuilt Audio Codec (ADC) - This is the first GS to feature a built in audio codec (ADC), eliminating the need for external audio connection to the PC sound card, this enhancement has significantly improved the signal to noise ratio and ease of use.

2000V Bias SHV Connector -  Unlike the GS-1100A and 1100-PRO, the GS-USB-PRO comes standard with an SHV connector for the high voltage bias and BNC connector for the optional signal input, making it compatible with most brands of detectors. 

Adjustable Volume and Pulse Shape - New features on this model allows the user to trim the preamplifier pulse gain and shape via separate trimmer potentiometers accessible without opening the enclosure, very convenient for optimisation of the dynamic range.

Larger Enclosure and Voltage Display - allows for more space between connections, making the unit easier to use when connecting and disconnecting cables. 

Combination Audio Jack - The analogue line level signal output used on the GS-1100A and 1100-PRO has been retained even though it is no longer required for use with a PC, but for those wanting to connect an iPad or iPhone there is a dip switch under the unit for switching between mono jack and TRRS  headset connector.

Right Channel Input - The audio jack right channel functions as an input, making it possible to connect two units together with a stereo crossover cable for coincidence counting. Custom made stereo crossover cables available to order.
