Functional Performance Test Alternatives
Measurement Option
Battlefield operational testing
Flight/field testing
Custom environment simulators
Off-the-shelf signal simulator
Considerations
Situation dependent, high risk, real operational conditions
Very expensive, some environmental control
High repeatability, high development costs, customized
Affordable, reconfigurable, moderate realism

Simply key in the width for the band power marker
Use Case: Make channel power ,adjacent channel power and C/N type
measurements using band power markers!
Marker Function: Band Power/Band Density Markers
Band density is same as band power except normalizes the power to the band width
•A user can have Band Functions on different traces (and Deltas
between them)
•A user can have Band Functions on stored traces!
•A user can have up to 12 band power markers!

90000A Series Continues to Deliver the Following Values:90000A Series Continues to Deliver the Following Values:
• You have great signal integrity, but need a little more memory to capture my entire signal.
• I need a scope which support full BW on all channels.
• Your InfiniiScan is great, but I need to capture infrequent events and signals as well.
• A scope is a large ADC to me. With longer memory, the speed of data transfer is critical.
• I want a bit more visibility with your display.
• I need a scope telling me the truth about my signal. I need accuracy and repeatability!
• Scopes are so expensive these days. Can anybody give me a true investment protection?
• 1Gpts per Channel Ultra Responsive Deep Memory
• 13GHz BW & 40GSa/s sampling rate on AllChannels
• Industry’s Only 3 Level Sequence Trigger System combining HW Trigger & InfiniiScan SW Trigger
