Summary
• Testing with pulsed-RF is very important for radar, EW, and wireless comms systems
• Narrowband detection:
• Spectral nulling technique improves measurement speed
• For radar and wireless comms applications, offers superior dynamic range/speed
• No lower limit to pulse widths
• Although the PNA uses different hardware and detection techniques
than the 8510, measurement results are essentially the same!
• PNA also offers numerous platform benefits:
• Measurement flexibility (32 channels, 64 traces, 16 windows, 16,001 points)
• Connectivity (LAN, USB, …)
• Automation (open Windows®, COM, SCPI …)
• Ease of use (built-in HELP, Cal Wizard, ECal …)
