About Tektronix Analyzers Your Tektronix Analyzer
Your Tektronix Analyzer
The SPECMON3 and SPECMON6 Analyzers will help you troubleshoot the toughest transient
interference issues by eliminating the guess work when using conventional instrument. Built-in mapping
supports both manual and automatic “drive test”. The revolutionary DPX display offers an intuitive
live color view of signal transients changing over time in the frequency domain, giving you immediate
confidence in the stability of your design, or instantly displaying a fault when it occurs. This live display
of transients is impossible with other signal analyzers. Once a problem is discovered with DPX, the
Tektronix Analyzers can be set to trigger on the event, capture a continuous time record of changing RF
events and perform time-correlated analysis in all domains. You get the functionality of a wideband vector
signal analyzer, a spectrum analyzer and the unique trigger-capture-analyze capability of a Real-Time
Analyzer – all in a single package.
Discover
DPX Minimum Event Time Capture: 3.7 μs (Option 110), 3.7 μs (Option 85), 3.9 μs (Option 40),
4μs (standard).
Trigger
Patented DPX Density Trigger (Option 200), Frequency Mask Trigger (Option 52) and advanced
triggering allows signal capturing with as short as 3.7 μs in frequency domain and 9.1 ns in time
domain, best in its class
Capture
All signals within a 110 MHz bandwidth span arecapturedintomemory(Option110only,85MHz
acquisition bandwidth with Option 85, 40 MHz acquisition bandwidth with Option 40, and 25 MHz
standard)
Analyze
Extensive time-correlated multi-domain displays connect problems in time, frequency, phase and
amplitude for quicker understanding of cause and effect when troubleshooting.
Power measurements and signal statistics help you characterize components and systems: ACLR,
Multi-Carrier ACLR, Power vs. Time, CCDF, Phase Noise, and Spurious.
