How Do I Use the Promira Serial Platform to Simulate an eSPI Master?

Question from the Customer:

Can I use the Promira Serial Platform to act as a master for the eSPI protocol? Would the eSPI Analysis Application work for this?

Response from Technical Support:

Thanks for your question!  The Promira platform can be used to simulate an eSPI master.  However, the Promira eSPI Analysis Application is not capable ...

What Are the Principles of the HEO and VEO Measurements with the Advanced Cable Tester?

Question from the Customer:

I need to test cables that are in development. Before I get started, I have some questions about the Advanced Cable Tester:

  1. How does the Advanced Cable Tester obtain the HEO and VEO measurements of the eye diagram? What test principles are used?
  2. What are the units of HEO & VEO? When I use an oscilloscope to view an ...

How Do I Set the Target Level Supply Voltage for an SPI Device for less than 3.3V using the Promira Serial Platform?

Question from the Customer:

I am testing SPI slave memory chips on an in-house test board. Some of the products we design have voltage specifications of 1.2V or 1.8V VCC and VCCIO.  Can the Promira Serial Platform source target devices at those levels? My current understanding, the VCC target supply is limited to 3.3V or 5V. Is there a way to ...

How Do I Implement I2C Master Register Read with the Aardvark I2C/SPI Host Adapter?

Question from the Customer:

I am using the Aardvark I2C/SPI Host Adapter with Aardvark Software API via Python and I need to communicate with registers. I noticed that the Python API supports functions aa_i2c_write and aa_i2c_read, which perform I2C Master write and I2C Master read respectively.  Is there an API function to perform I2C Master ...

I am using the A2B Bus Monitor and I can see the I2C transactions during “discovery”, which indicates the monitor is up running and monitoring the A2B bus. However, the audio output is not visible.  How do I configure the A2B Master to enable monitoring the audio output?

Response from Technical Support:

Thanks f...

How Can I Best Verify MOSI/MISO SPI Data Traffic Using the Aardvark I2C/SPI Host Adapter?

Question from the Customer:

I am using the API functions to control the Aardvark I2C/SPI Host Adapter in SPI mode. To loop the MOSI/MISO, can I use only one Aardvark adapter or do I need two Aardvark adapters?

Response from Technical Support:

Thanks for your question! To test the traffic as you described, you will need two Aardvark adapters. On...

How Do I Acquire and View Audio Details with the Data Captured by the A2B Bus Monitor Using Python Scripts?

Question from the Customer:

I am using the Promira Serial Platform with the A2B Bus Monitor – Level 1 Application. I have questions about using the A2B API software.

  1. Does it contain information about Level (dBFS) and Frequency (Hz) in the uncompressed PCM file from audio_capture.py, promira.py?
  2. ​Where can I find information for the command...

How Do I Identify which I2C Host Adapter is Connected to which Port using LabVIEW?
