Loading...Why does the noise floor increase at channel turn on in Agilent Technologies Measuring Instruments?
If the noise floor increases when you turn on a channel, it might be because the channel uses a different scramble code than the one set in the Agilent Technologies Measuring Instruments. To fix this, change the scramble code used to transmit the channel to match the one used by the Perch channel.
What to do if wrong channels are marked as active in Agilent Technologies Measuring Instruments?
If wrong channels are marked as active on your Agilent Technologies Measuring Instruments, it could be due to a poor signal-to-noise ratio. Increase the signal power or remove the source of noise or distortion. Ensure all bits are transmitted within a physical channel, or select code-domain power for the layer associated with the physical channel of interest. If time gating is on and the gate length is less than 3 slots, select 3 or more slots or turn off time gating.
