ANALYTICAL INSTRUMENTATION

“What you set is what you get” feature helps you avoid losses, mis- match errors, and uncertainty contributions introduced by cables, other devices and interconnections, eliminating complex setups and time consuming methods otherwise required to obtain accurate results.

Conclusion The 96270A can ‘self-characterise’ or profile its output to account for losses and attenuation of system components like cables, attenuators, splitters, and connecters, effectively creating a signal reference plane directly at the connection to the UUT input. This frequency or amplitude level correction profile is saved into 96270Amemory, which can store up to 30 profiles for different output and interconnection configurations. Using a profile, the 96270A applies the level correction data automatically and delivers the user’s signal level setting accurately at the reference plane created at the UUT input. -100 -110 -120 -130 -140 -150 -160 -170 1 Hz 10 Hz 100 Hz 1 kHz 10 kHz 100 kHz 1 MHz 10 MHz 100 MHz Offset Frequency 96270A 96270A with the 9600-FLT filter
