Positioning Application: PosApp reports error message "incorrect number of channels for output 1" with GSS6700
This error message occurs when there is a mismatch between the sig_gen.txt and the signal generators capability. For example, your sig_gen.txt may be setup for 12 channels but your GSS6700 may be capable of simulating 24 channels (figure 1)
The main cause for this error is likely to be that you have recently upgraded your signal generator with the use of a feature key but you have not installed your new sig_gen.txt in the PosApp directory. If you have not received a new sig_gen.txt when being supplied with a feature key please contact
and quote the serial number of your unit.
If you were to have too many channels on your sig_gen.txt you would see an error similar to that in figure 2. In this example your sig_gen.txt is setup for 36 channels, but your GSS6700 is only capable of simulating 24 channels.
If you have recently received a new sig_gen.txt from Spirent Communications due to a feature upgrade it is possible that you see the above error message because you have installed the new sig_gen.txt but not completed the feature upgrade of your GSS6700.
If this is the case please follow the steps found in
If you have followed these steps and the error message remains please contact
and quote the serial number of the signal generator and the feature key being used.
