8164B data fetch speed

Solved!
Go to solution

Hi

 

I am using Labview 14 for data logging from Agilent 8164B Lightwave Measurement System using GPBI USB HS. My problem is that I need to log the data every 1 ms. However, I can not reach this speed. I got only 30 measurements per second (33 ms). I have attached the labview code. 

 

In the equipment datasheet, it is written "GPIB interface performance: Max. 300 kB/sec (burst data rate during read of 12001 data points from power meter)"

Hi majed,

 

the user manual of your Agilent device surely also mentions the measurement speed.

And this specification is quite different from and not (at all!) related to GPIB bus speed!

Hi

 

In the datasheet, it is mentioned that the following:

 

GPIB interface performance:  Max. 300 kB/sec (burst data rate during read of 12001 data points from power meter)

 

So will this allow me to fetch the data in 1 khz speed?

Hi majed,

 

there surely is more in the manual than just this one sentence…

 

burst data rate during read of 12001 data points from power meter)

This is valid when the data is already available in the device's internal buffer!

 

So will this allow me to fetch the data in 1 khz speed?

This question is answered in the manual. What does it mention on sample rates of your device?
 
Again: GPIB bus speed is NOT related to sample rates of your device!
Please read the manual, I can't as Agilent requires a login to download this PDF…
Best regards,
GerdW

Thank you.

 

I found it in the device manual downloaded form keysight. By the way, you dont need an acount to dowlaod the keysight files. Just put your information and click download.

 

Thanks again.
