Issues in E4406A capturing the Tx demodulated data bits

Dear All,

I have a GSM 900 signal source. From that I have sent the one timeslot for every 577 micro seconds interval.

Please find the attached screen shot for your reference.

I have a driver for E4406A capturing the Tx demodulated data bits. But in that driver I can capture only 250 timeslot per minute. But my signal source send the 1700 time slot per minute.

I have some questions below:

1.Is there is any driver or SCPI command is there for capturing the all the Tx demodulated data bits?

2.Is VSA AE4406A demodulates all the timeslot packets for phase and frequency error measurements?

3. Can anyone please tell me, how the VSA internally demodulates the timeslot packets for Phase and frequency error measurements?

4. Whether the VSA randomly take one time slot at some regular interval and demodulate it for Phase and frequency error measurements?

Please send me your valuable comments
