Functional Features
Pulse S-parameter measurement
Built-in 4-way pulse generator for internal source modulation, IF gate control, and output from the rear panel. The pulse width and delay time of each pulse generator can be set independently.
The source modulation sources include rear panel input, internal pulse generator and various states such as normally open and normally closed, which can either modulate the source of the vector network analyzer by using external pulses or keep it in continuous wave state and measure it by triggering the synchronization mode, which can provide powerful support for the testing of T/R components, antenna transceiver modules and so on.
Mixer/Inverter Scalar
Measurement and Analysis
Provide perfect mixer/converter characteristics settings, support double-order local oscillator, external local oscillator source input; support linear sweep, power sweep, segment sweep and other sweep types; through simple settings can automatically complete the complex mixer RF, dual LO, IF multiplier, crossover and other characteristics of the calculation; support the source port power, the local oscillator port power, attenuation, power sweep characteristics settings, etc.
Mixer/Inverter Vector
Measurement Analysis
Provides complete mixer/converter amplitude response, absolute phase and absolute time delay response measurement capability. Dual mixers are introduced during the calibration process to realize the frequency conversion of the reference path and the calibration path. The introduced dual mixers require the same frequency characteristics as the DUT and the calibration mixers require reciprocal frequency characteristics.
A single connection can be made to complete the mixer/converter complex characterization with high amplitude and phase measurement accuracy.
Gain Compression Measurement
Gain-compression measurement function can complete the measurement of linear gain, compression point gain, compression point input power, compression point output power, linear input matching and other compression parameters of active devices in the working frequency band through one connection and one calibration.
Gain-compression scanning
3D drawing
Provide 3D view function, better show the working performance of the measured parts in the excitation state, in addition to the frequency section and power section can be displayed, can intuitively show the characteristics of the measured parts at each frequency point and each power point.
Noise figure measurement
A single connection allows simultaneous testing of a wide range of parameters such as S-parameter, noise figure, noise parameter, gain compression and inverter gain. Based on the cold source noise figure test method, accurate noise figure and noise parameter tests can be performed. By constructing an advanced noise correlation matrix model, combined with the vector network analyzer's precise S-parameter calibration, it is suitable for accurate testing of smaller noise figure DUTs. Measurement dynamic range of up to 55 dB, suitable for testing large gain DUTs.
Spectrum Measurement and Analysis
Each port of the vector network analyzer can complete the measurement of the input spectrum and output spectrum of the test piece, which can quickly locate the state of the spurious spectrum and harmonics of the test piece under a small resolution bandwidth.
For active device testing, the spectrum measurement function can provide more measurement parameters, a single instrument through a single connection can realize the routine S-parameter testing, spurious and harmonic localization measurement; complete ratio and absolute measurement error correction technology can provide more accurate measurement results.
Signal Integrity
Measurement and Analysis
Powerful signal integrity measurement and analysis capabilities, providing micron-level spatial resolution. Simultaneous time-domain and frequency-domain test analysis in a single view allows accurate testing of changes in impedance characteristics on the transmission line; convenient near-end and far-end crosstalk testing is used to test the extent to which multiple transmission lines interact with each other.
The advanced time-domain analysis option features virtual eye diagram generation and analysis based on network parameters. Depending on the high-speed digital communication standard, the advanced time domain analysis option can use pre-defined eye diagram templates for efficient Pass/Fail testing.
Total Harmonic Distortion (THD) measurement and analysis
Wide bandwidth test, can be used for true differential excitation under the input and output power, gain, harmonic total distortion and other parameters of the analysis, simplify the harmonic performance of differential devices test complexity.
A single calibration simultaneously completes the error correction of multiple channels. The editing of setup and measurement parameters can be carried out by means of XML files, and parameter import can be realized with one key.
Automatic Fixture Removal
For non-standard connector device testing, such as packaged microwave devices, on-chip devices, etc., such devices cannot be directly connected to the vector network analyzer. Often fixtures are used to connect the DUT to the vector network analyzer, but fixtures also introduce measurement errors. The automatic fixture removal function extracts, stores and de-embeds fixture parameters to obtain the true parameters of the DUT.
