Hi...I am using PNA-X N5242A to generate pulsed RF signal. I want to generate the pulsed RF signal from port 3 of PNA. I am trying to configure the pulse from "Pulse Setup" window.

I am listing my configuration below to generate pulse from port 3

*INTERNAL PULSE GENERATOR*
"Enable" Pulse 0
"Enable" Pulse 1

*INTERNAL PULSE MODULATORS*
"Enable" Enable source 1 modulators

*MODULATOR DRIVE* 
Pulse 1

*PULSE MEASUREMENT*
Standard pulse

*Trace S43*

*Freq. Range: 3.1GHz to 3.5 GHz*

But when I am trying to see the generated pulse on CRO. I am not getting a stable pulse. Pulse is sweeping from left to right. 

Is there any other setting which is require to generate Pulsed RF signal from Port 3 of PNA. Please correct if I am wrong.
