Title: Keithley/Tek DMM6500 streaming troughput 16bit mode.
Post by: miro123 on January 23, 2024, 04:48:34 pm
Hello TE expert,
I have one question related to Keythley DMM6500.
I want to use the multimeter to capture continues data in high speed 16bit mode.
What is the LAN throughput without loosing any samples.I need all data to be collected to PC for let say 1..2weeks .
The datasheet Page 11 table "Bus Transfer Speed " gives only average numbers for 1000 readings

Thanks in advance
Miro

60 kilo samples in second.

They have a PC application that can capture data continuously. They promise 60K/s

Thanks I alredy received my DMM6500. I will try and test it using python via LAN interface. I already have it running on standart /low speed mode/ using RAW socket interface.

According to spec is "Average for 1000 readings with relative timestamp (binary) LAN 160,000Sps

How’s it going with your testing on this?

USB will be faster. Keithley also says this in one of their docs (1KW-61357-0_DMM6500_Datalogging_Application_Note_080318). The LAN interface is 100BT only, the USB 2.0 interface can go up to 480Mbps.
