Network Analyzer

Hi,

When I refer to the Agilent 4396B Network/Spectrum/Impedance Analyzer Function Reference on Page 10-2 Specification, it is stated that the the full scale input level for channel A and B is -5dBm. What does full scale input level mean? What would happen if the input signal is larger than that?

Next, I have a circuit which attenuates signal of (-30dB) and I would like to test the frequency response using a 10dBm source power signal. However, before testing the circuit, I tried to calibrate the response of network analyzer and there was an error message warning that the input signal is overloading the channel B. I connected the output of the RF source to a power splitter and two output of the power splitter is connected to the R and B channel of the network analyzer respectively. How could I overcome this problem so that I could calibrate the network analyzer and use a large signal to measure the response of the circuit?

Kindly advise.
