Across

3 ENOB (4 words)
5 A technique used with oscilloscopes and spectrum analyzers to reduce noise and
effectively increase resolution and dynamic range
7 A load-pull technique that uses a separate coherent signal source to stimulate the
source or load side of the DUT, thus removing any uncontrolled interaction between the
DUT and load-pull system (3 words)
13 Vector signal analyzer
14 Short for Digital Storage Oscilloscope
15 Bigger brother of PXI
16 Tektronix has developed a high performance display technology called ______
17 Vector Network Analyzer
19 Time variation of a periodic signal
20 FTT (3 words)
21 A key figure of merit for an oscilloscope that needs to be specified by fractional
bandwidth and at the frequency of interest (4 words)

Down

1 Short for PCI extensions for instrumentation
2 Short for Mixed Signal Oscilloscope
4 XCO (2 words)
6 Passive tuners with multiple slugs/sliding shorts that allow some control of harmonic
impedances (2 words)
8 While most high performance oscilloscopes use SiGe-based ICs, Agilent has
implemented high speed ICs using this material (2 words)
9 Error Vector Magnitude
10 Power Added Efficiency
11 PIM (2 words)
12 DUT (3 words)
