Rohde & Schwarz R&S ZVL13 – The Four-in-One Vector Network Analyser that covers Microwave applications

Cost-Efficient ▪ Multi-Purpose ▪ Compact ▪ Future-Proof Instrument

Reasons to Consider the R&S ZVL13 Vector Network Analyzer

• Addresses microwave applications up to 13.6 GHz
• Measures uplink frequencies of satellite Ku band at 15 GHz overrange
• An option (ZVL-K1) to enable a full spectrum analyzer (R&S FSL)
• Completely bidirectional two-port network analyzer as a standard
• Calibrate cables, antennas, and coupling networks for conducted measurements using low start frequency at 9 kHz
• Portable for field applications via DC/battery power operations
• 4-in-1 instrument shortens design and production times, andsimplifies single connection component / device testing

How The R&S ZVL Will Meet Your Needs
Research & Development Small Design Labs Friendly – ZVLs help small design labs to optimize bench space and to remain within capital expenditure budgets.

Production High Throughput – Remote controlled switchover from VNA to SPA, and vice versa; and 500 kHz bandwidth supports short measurement times.

Satellite Communications Ku band Uplink supported – With 15 GHz overrange, ZVL13 measures 14 to 14.5 GHz uplink frequencies of DVB-S (Astra or fixed svc. satellite).

Mobile & Wireless Comm. Spurious Emissions Measurements – Dynamic range of >100 dB and 13.6 GHz frequency range is ideal for manually tuning diplex filters.

Field Use / Mobile Applications Light Weight & Compact Form Factor – 15.4 lbs (7 kg), battery and DC operations support portable and mobile uses.

Installation & Service Multi-Purpose Instrument – Combination network analyzer, spectrum analyzer and power meter in a single instrument increases work efficiency.

R&S ZVL13 Applications Include:

• Satellite Communications – support of uplink frequencies in Ku band
• Mobile Communications – manually tuning of diplex filters of base stations
• Universities – wide range of functions supported on one instrument with a low price
• Small Design Laboratories – multi-function instrument
• Manufacturers – cables, connectors, combiners, diplexers, switches, etc.
• Field Services & Installation – small form factor and lightweight

What Makes the R&S ZVL Vector Network Analyzers a Great Value?
All R&S ZVL instruments operate as Network Analyzers, Signal Analyzers, Spectrum Analyzers and high accuracy Power Meters in one. The 9 kHz start frequency addresses the commercial EMC standards, and are important in calibrating cables, antennas or coupling networks for conducted measurements.

The new R&S ZVL13 going up to 13.6 GHz addresses the stop band attenuation of filters for base stations, and measures uplink frequency of Ku band satellite systems.

As multi-function instruments ZVLs serve to reduce design time and improve production throughput. Portability with DC and battery operation in a compact and light weight form factor, makes it just the right instrument for mobile applications, such as field installation and on-site service & maintenance.

Wander is defined as the phase error comprised in the frequency band between 0 and 10 Hz of the spectrum of the phase variation. If this frequency is higher than 10 Hz, it is known as Jitter. Jitter is the time variation characteristic of a periodic signal in electronics and telecommunications, often in relation to a reference clock source. Jitter may be observed in characteristics such as the frequency of successive pulses, the signal amplitude, or phase of periodic signals. Jitter is a significant and undesired factor in the design of typically all communications links. Jitter can be quantified in the same terms as all time-varying signals (RMS, Peak-to-Peak Displacement), also like other time-varying signals, Jitter can be expressed in terms of spectral density. Jitter period is the interval between two times of maximum or minimum effect of a signal characteristic that varies regularly with time. Jitter frequency, the most common figure, is its inverse. Very low Jitter frequency is not a standard interest in designing systems, and the low-frequency cutoff for Jitter is typically specified at 1 Hz.

Types of Jitter

• Random Jitter or Gaussian Jitter, is an unpredictable electronic timing noise.

• Deterministic Jitter is a type of clock timing Jitter or data signal Jitter that is predictable and reproducible. (AKA Periodic Jitter, Data-Dependent Jitter or Duty-Cycle Dependent Jitter)

Testing for Jitter and its measurement is of great importance to electronics engineers because of the ever increasing clock frequencies in digital electronic circuits aimed at achieving higher device performance. Testing of device performance for Jitter tolerance often involves the injection of Jitter into electronic components with specialized test equipment. Jitter is measured and evaluated in various ways depending on the type of circuitry under test and the goal of Jitter measurement is to verify that the Jitter will not disrupt normal operation of the circuitry.

Some popular T&M equipment used for Jitter testing:

Lecroy WavePro 715Zi Digital Oscilloscope with the Jitter and Timing Analysis Package (WPZi-JTA2) WPZi-JTA2 adds Specialized timing parameters measure period, cycle-cycle, half period, width, etc. Jitter on a variety of signals. Use the three views of Jitter (statistical, time, and frequency) to understand root cause and to debug problems. Histograms provide understanding of statistical distributions. Tracks provide a means to show time-correlated peaks of Jitter, and compare to other signals. FFTs provide the ability to debug root causes of high in-circuit Jitter.

Agilent 37717C Communications Performance Analyzer can be configured as a dual standard SONET/SDH analyzer for BER and Jitter tests which makes it the ideal tool for testing network equipment in a manufacturing environment.
