Achieve Clarify Faster - Frequency Domain Performance (Continued)
Trying to interpret traditional oscilloscope time-domain specifications can be challenging when trying to determine if a specific scope
can be recommended for RF, µW, and mmW measurements� With correction filters, low-noise front end and spurious free dynamic
range calibration, the V-Series oscilloscopes can be used for wideband frequency domain applications�
V-Series typical values (tested at 33 GHz bandwidth, 1
channel on one scope unless noted)

Typical frequency domain characteristics for the Infiniium V-Series (not guaranteed, subject to change)�
Using data acquired from the V-Series, VSA shows an excellent third
order intercept (TOI) value of 26 dBm�
Using data acquired from the V-Series, VSA shows an error vector
