Insertion loss measures the energy absorbed by the transmission line in the direction of the signal path in dB/meter or dB/feet. In wireless communication systems, the transmit and receive antennas are connected to the radio through coaxial cable and/or waveguide transmission lines (Figure 1). This application note explains how Site Master is used to measure cable insertion loss with different test methods and how to predict the maximum allowable cable insertion loss through manual calculations. Insertion loss measurement is one of the critical measurements used to analyze transmission feed line installation and performance quality. All Instacal All All en Drivers.Transmission feed line system performance plays an important role in wireless network coverage. Programs that were created before June of 2000 will need Instacal installed in C:\CB. You may need to install Instacal in a different directory than the default of C:\MCC. Some software developers embed the installation path of Instacal into their programs. Upgrading from 16 bit versions of Instacal to 32 bit. The Demo board is installed by default, but if it has been removed you can install it as follows: To install the demo board, run Instacal, click the " " button on the left end of the too. How do I emulate hardware using Instacal? I need to develop software but I do not have the Measurement Computing hardware on the development machine.Ģ It is possible to install a "Demo board" in Instacal, which provides emulation of Analog Input and Digital I/O. If checking the board number does not reveal a solution, this problem can also be caused by additional copies of CBW32.DLL on your hard disk. Instacal detects my hardware, but my Universal Library application returns Error 1 "Invalid Board Number".Į Check that you have set the correct board number in the application, and that it corresponds to the board number assigned in Instacal. The calibration procedure is launched from Instacal (select the card and open the "Calibrate" menu, and select A/D.) The calibration procedure displays st. For optimum accuracy, calibration should be carried out every 12 months. How can the PC-CARD-DAS16/12 or PC-CARD-DAS16/16 be calibrated?Į To calibrate the PC-CARD-DAS16/12 you will need a precision DC source. Instacal may need to be installed in a different directory than the default of C:\Program Files\Measurement Computing. Upgrading Instacal with 3rd party programsĮ Some software developers embed the installation path of Instacal into their programs. The Universal Library requires you to specify the board number in each funct. It is not the same as the board serial number, as it is recorded only in the CB.CFG configuration file created by Instacal. There should only be one copy, in the main Instacal installation folder (typically C:\program files\measurement computing\daq\ or C:\MCC on older systems.Ħ The board number is assigned by Instacal to each Measurement Computing board installed on the PC. Error number 308 has no text when running Instacal.Ī Check for duplicate copies of CBW32.DLL on the PC by searching the entire hard drive, including system and hidden files, for files of this name.
