I'm trying to get 10 to 20 fresh samples from the Nanovoltmeter into a custom GUI using serial communication.

Serial communication requests (:sense:data:fresh?) using the pyserial library take an average 0.080 ± 0.057 s to return, and as much as 0.285 s.
 

• Question 1: Is there anything I can do on the Nanovoltmeter side to improve the time it takes to get a value back, or am I limited by serial communication?
• Question 2: Is it possible to get N samples, sampled as fast as possible, in one serial request?

Here are my initial settings, which I use in the initialization of every python object of my nanovoltmeter class:

*rst
*cls
:init:cont off;:abor
:sens:func 'volt:dc'
:sens:chan 1
:sens:volt:chan1:rang:auto on
:sens:volt:chan2:rang:auto on
:syst:azer on
:syst:lsyn off
:outp off
:sens:volt:chan1:dfil:stat on
:sens:volt:chan2:dfil:stat on
​​​​​​​:sens:volt:chan1:lpas:stat off
​​​​​​​:sens:volt:chan2:lpas:stat off
:sens:volt:nplc 1
:disp:enab on
:form:elem read
:trig:del 0
:trig:sour imm
:trig:coun inf
​​​​
Many thanks!
