LVDS POD

LVDS Probe is only for LA4000/3000 series & BusFinder series. LVDS Probe can be applied to logic signal and low voltage differential signal(LVDS) measurement.

• LA08/09 Tip: Digital signal input channel. It contains 2 LA09-tip & 1 LA08-tip for single-ended signal measurement.

• LVDS Tip: Low voltage differential signal input channel. It contains 8 pairs of differential signals in the LVDS-tip

LVDS, as a commonly used high-speed data transmission standard, requires dedicated probing tools for signal analysis and measurement. It finds extensive applications in high-speed data transmission systems, image processing, industrial automation, and other fields.

Signal Compatibility:
LVDS logic analyzer probes should exhibit good signal compatibility, capable of adapting to different types and standards of LVDS signals.

Measurement Range:
The probes should cover the typical LVDS signal range, including the general voltage range of 200 mV to 1200 mV, to ensure accurate measurements.

Excellent Common Mode Rejection Ratio (CMRR):
The probes should have excellent CMRR to reduce the impact of common mode interference on measurements, ensuring precise signal analysis.

Differential Acquisition Capability:
The probes should effectively capture LVDS differential signals, maintaining signal integrity and reducing signal distortion.

Low Interference and Noise:
The probes should possess outstanding interference resistance, minimizing external interference and noise"s impact on measurements.

Specifications are as follows:
• Threshold：NA (LVDS P/N reference)
• Input Voltage：Max=0~3.3V
• Sensitivity=100mV
• Impedance：75kohm || 3pF
• Data rate：500Mbps (Same as LA-probe)

Logic Analyzer (LA) Mode

• Capture digital waveforms and support bus decodes. Able to stack with a DSO to form as an MSO.

•  Provides multiple storage modes, users could select to have long time recording or precision acquisition.

•  Long Time Record: Transitional Storage VS Compressed Storage

For signal capture and analysis, usually require to record the signal for a long time. If the data is stored in a compressed way, it will cause your software to lag or even stop functioning when decompressing the data after it is sent back to the computer. Because PC memory size might insufficient for decompressed data size. To satisfy the requirement of smooth software operation and long-term recording without missing any data, the storage method adopted by the Acute analyzer is transitional storage rather than compression. After returning to the PC software, it doesn"t need to do the decompression. The decoded results can be displayed while the analysis is finished.

Protocol Analyzer (PA) Mode
It is hardware decoding, may log protocol data very long time if without waveforms. Application timing: Preliminary protocol debug.

Protocol Analyzer	Protocol Logger	Protocol Monitor
Show real-time protocol data. Application timing: massive protocol data with some idles in between.	Like data logger, save massive data into SSD hard drive. Application timing: massive protocol data.	Like dash cameras, record protocol data by the device’s memory only. Application timing: trigger event only happens in very long time.
