With OML (a) and Virginia Diodes (b) extenders.
In the analog portion of the block diagram, the next step is extending SA capabilities into the terahertz region while retaining the expected functionality, performance and accuracy of VNA and SA measurements.įigure 1 The addition of solution-partner frequency extenders to the PNA enables a banded terahertz solution.
Recently, faster digitizers, digital signal processors (DSP) and central processing units (CPU) have enabled Keysight to implement an SA capability that is fast enough to accelerate crucial - and often tedious - measurements, such as the search for spurious signals. One solution is to incorporate VNA and SA capabilities into a single instrument. It can also introduce measurement errors, extend measurement time, and damage the probes, the test cables and even the DUT. During a typical measurement session, the need to frequently connect, disconnect and reconnect the device under test (DUT) is both inconvenient and time-consuming. To further complicate the situation, achieving an insightful understanding of component performance and behavior often requires two instruments: a vector network analyzer (VNA) and a spectrum analyzer (SA).
Device characterization can be challenging and complicated when venturing into the terahertz frequency range.
