Pulse generation from PNA N5242A

Hiii... I am using PNA N5242A for generating pulsed RF signal. I am able to generate pulsed RF signal from PNA using LabVIEW GPIB commands but now I am facing two problems

1. when I am configuring pulse from LabVIEW at 10uSec pulse width & 10mSec pulse period (1% Duty Cycle) in PNA then IFBW automatically set at 50Hz & after that I am not able to change the IFBW but it should be greater than the reciprocal of T ON time of pulse.

On the other hand when I am configuring the pulse Manually at 10uSec pulse width & 10mSec pulse period (1% Duty Cycle) in PNA then IFBW automatically set at 150KHz.

At IFBW 150KHz my reading are better. How to configure IFBW after configure pulse programmatically in PNA?

2. When I was seeing Generated pulse RF signal on CRO using Peak Detector, I found that generated pulse has a ramp with positive slope in its High State & also has rise & fall time greater than 400nSec. 

Is it a PNA problem or I have to use some other settings to correct the generated pulse
I am attaching snap shots of generated RF pulsed Signal
