Transform your Timer/Counter into a Modulation Domain Analyzer
With the TimeView™ analysis software, you can transform your Tektronix FCA or MCA Series timer/counter into a Modulation Domain Analyzer (MDA). An MDA displays frequency versus time, just like an oscilloscope displays voltage versus time. With an MDA on your bench, you will be able to completely characterize your signal.
Dynamically analyze your signal's amplitude and frequency
The modulation domain (f versus t) complements the time domain (v versus t) and the frequency domain (v versus f) to provide a complete picture of your signal.
Amplitude and frequency content are the two most important properties of any signal. Oscilloscopes are used to analyze changes in amplitude over time but not changes in frequency. The traditional tool for analyzing signal frequency content is the spectrum analyzer. However, this can only find static frequency components or give an averaged view of dynamic (changing) frequencies.
The modulation domain is the “missing domain” that complements the time and frequency domains. TimeView is the software that works with the Tektronix Timer/Counter/Analyzer FCA3000, FCA3100, and MCA3000 Series (through USB or GPIB) and converts them into a Modulation Domain Analyzer.
Simple to setup and easy to use
Using TimeView is as simple as connecting your Tektronix FCA or MCA Series timer/counter to your PC. Tektronix timer/counters offer both a USB port and a GPIB port to simplify this connection. Once connected to TimeView, you remotely control the product with all the same setup and analysis features found on the product.
The fast sampling front-end of your timer/counter will sample the frequency (or time, or phase, or voltage if selected) then transfer that data to your PC. TimeView will then post-process the data and display the results in a variety of formats, depending on your selection:
- Modulation domain (frequency versus time)
- Continuous time stamp (trigger events versus time)
- Time domain (voltage versus time for repetitive signals)
- Any measured parameter versus time
Graphs can be printed, and settings and results are stored as ASCII-files that are easily imported in various programs such as Microsoft Excel for further analysis.
Analyze your device with the industry's only Modulation Domain Analysis software
You will find the MDA to be a very versatile tool, especially suited for R&D engineers, but an MDA also fits in the RF service lab and in metrology labs. You have all the same measurement capabilities and analysis tools as the product, but with the ability to view and analyze your signals over time. A few applications that otherwise would be impossible, or very expensive to carry out are:
- Visualize frequency-hopping patterns in FHSS frequency-agile communication, missile guidance systems
- Measure frequency stability per individual channel in TDMA communication systems
- Measure frequency droop on individual channels in frequency-hopping systems
- Analyze chirp radar performance
- Measure pulse jitter and view distribution histograms
- Calibrate frequency-sweep signals
- Calibrate intentional modulation (FM or FSK)
- Discover phase jumps in synchronization clocks
- Measure frequency settling times of VCOs
- Characterize start-up/warm-up of oscillators
Jitter (RMS and peak-peak) and noise is quantified with distribution histograms.
The FFT diagram reveals the modulation frequency, whether intended or unwanted.

Mode Description Free-running Measurements Measurements are captured as quickly as possible and stored in internal memory. FCA/MCA3000 <4 µs dead-time between measurements. Repetitive Sampling Measurements are repeated with a delayed start that is incremented for each new measurement. The results are combined into a resulting graph (similar to repetitive sampling DSOs). This capture mode requires a repetitive signal. FCA/MCA3000 Down to 10 ns delay between measurements (effective 100M Samples/s). Waveform Measurements This capture mode requires a repetitive signal. FCA3100 Voltage resolution is 1.0 mV FCA/MCA3000 Voltage resolution is 3.0 mV Zero Dead-time Time-stamping Capture (FCA/MCA3000 family only) Frequency Range DC to 250 kHz (capture and time stamp ALL trigger events).
