OSLT Calibration Kit, 2.92mm

SPARQs are available from 2 through 12 ports. The 8 and 12-port models are capable of characterizing crosstalk on multi-lane differential devices. For example, the 12-port SPARQ can simultaneously measure NEXT and FEXT crosstalk on up to 3 differential lanes, and is similar in price to a lesser-capable 4-port VNA.

Key Features

Title

The SPARQ signal integrity network analyzers connect directly to the device-under-test and to PC-based software through a single USB connection for quick, multi-port S-parameter measurements.
SPARQ is the ideal instrument for characterizing multi-port devices common in signal integrity applications at a fraction of the cost of traditional methods. It is ideal for:Development of measurement-based simulation models
Design validation
Compliance testing
High performance TDR
PCB testing
Characterizes crosstalk on multi-lane differential structures
Portable measurement requirements

High-bandwidth, Multi-port S-parameters for the Masses
S-parameter measurements are most often produced by a Vector Network Analyzer (VNA), a difficult instrument that is beyond many budgets. SPARQ is very affordable and simplifies measurements, making S-parameters accessible to all.

PC-Based, Small and Portable

S-parameters, Quick

Internal Calibration
SPARQ takes a revolutionary approach to calibration by building in calibration standards. This enables measurements to be made without multiple connection steps and removes the need for additional electronic calibration (ECAL) modules. Calibration proceeds quickly without user intervention, so one can calibrate often without resorting to the use of saved calibrations that are out-of-date and lead to incorrect measurements.

Includes the Tools That You Expect
A signal integrity network analyzer should include well integrated tools for providing measurement and analysis in both time and frequency domains. Signal integrity requires more than just S-parameters. The time-domain offers important insight as it shows the performance of the S-parameter models in simulation.
SPARQ includes all of the hardware and software tools standard to make signal-integrity measurements right out of the box. These tools include capabilities that cost extra on most instruments, including mixed-mode S-parameter conversion and port-renumbering, passivity, reciprocity and causality enforcement, and built-in time-domain views like impedance, rho, step response and impulse response. All time-domain results can be normalized to your system rise time.
The SPARQ hardware includes calibrated cables for each port, calibrated female 2.92 mm connectors for each port for adapting the connector gender, a universal wrench for holding most popular connector sizes, and a precision torque wrench.

Streamlined Setup
The simple setup shown in the main setup screen above is all that is needed to configure a SPARQ measurement. You provide the frequencies and number of ports and go. Helper information like time length help in frequency spacing choices and DUT length modes control the pulser repetition rate for faster measurements. Various measurement sequence control modes allow for trade-offs between dynamic range and speed with time estimates shown. All measurements proceed automatically without user intervention. Advanced screens are easily accessible for extra capability, including differential or mixed-mode measurements.

A Wide Variety of Measurement Types
SPARQ can perform all tests currently made with TDR or VNA instruments only easier. Some measurements and tests that SPARQ performs include:Impedance
Return loss
Impedance Imbalance
Insertion loss
Crosstalk (near- and far-end)
Differential- to common-mode conversion
Common- to differential-mode conversion
Intra-pair skew
Voltage transfer functions
Differential- and common-mode step response at input and output ports
Mode conversion step response
Both mixed-mode and single-ended measurements standard
Risetime normalization for all time-domain results
TDR and TDT mode

All measurements can be made in differential-mode, common-mode or single-ended, as applicable.
