How far can the Quasar really transmit data and can it go through walls?

In actual testing done at customer sites, using the high power option, there was not a place within 100 meters that we could not connect, including going through multiple walls that were made of drywall. The only time we lost transmission was when the walls were made of concrete or we had to pass through some metal doors. With normal labs and offices the signal went right through. In several cases, including a solar power scribing application where windowed doors had to be closed, we were getting a continuous connection as we walked around the spacious building into offices and labs. With the standard range option, the range should be about 1/3 of this i.e. 30 meters.

Which version of StarLab should I use with the Quasar

The Quasar is fully supported in StarLab version 2.40. StarLab 3.00 doesn’t support the Quasar.

At what frequency does the Quasar work? Might there be concerns with interference from other devices?

Quasar runs on Bluetooth, the 2.4-2.5GHz "ISM" band (ISM = Industrial, Scientific and Medical). This is the same band used by WiFi and other technologies. This frequency was chosen as it is available without restrictions around the world. Because other technologies also use it, Bluetooth has to be designed to tolerate interference from other sources. It does this by swapping between 79 channels, at 2.402GHz up to 2.480GHz (each channel is 1MHz). This type of modulation is called FHSS, Frequency Hopping Spread Spectrum. If data does not get through on one channel it retries on a different channel. Other technologies, such as WiFi, use different techniques.

 

This design makes Bluetooth very robust. In principle, if there is another radio transmitter nearby that is using the same 2.4-2.5GHz band AND using the same modulation scheme, interference is a possibility, but not a real likelihood. If the other transmitter is using a different band, there should not be a problem, because there is very little interference produced at other higher or lower frequencies - this is checked during qualification of these devices for CE and FCC in RF test labs.

 

In general, Bluetooth is in common use everywhere, by cellular phone headsets, for example, so interference is not normally a significant risk factor.

Will my Quasar work with my Android device?

Yes, we have an Android app that you can download from the Android Market place to run your Quasar on your Android device. Search for Ophir Optronics Quasar. You need to be running Android 2.3.3 or higher.

How do I pair the Quasar interface with my computer?

If using the Bluetooth radio USB adaptor supplied with the Quasar, the adaptor software should be installed first. Once that is complete, and the StarLab software installation is complete, you are ready to connect the Quasar. You may need to change the discovery settings on your PC to allow the Quasar to connect.
 

To accomplish this, go to the Bluetooth Settings on your PC and ensure you have checked "Allow Bluetooth devices to find this computer".

  • PC Software & Drivers

    This section describes various ways to interface the Ophir meter to your PC as well as the software options available.


     

  • StarLab

    The StarLab application together with an Ophir meter turns your PC or laptop into a full-fledged laser power/energy meter. Supports most Ophir laser power/energy sensors. Up to 8 sensors can be displayed at once on one PC. By using the Ophir COM Object, you can control the device from your own application. Supports the StarLite, Juno, USBI, Nova II, Vega and Pulsar-1/2/4 devices.

If all your laser measurement work involves a laptop or a PC, rather than a stand-alone meter, one of Ophir’s direct-to-PC interfaces could be an ideal solution. These are full-fledged Laser Power and Energy meters, but instead of having a separate on-board display, the PC becomes your display. In this video you will learn about the range of PC Interfaces available from Ophir.
