N9342C HSA - Read out Trace

Hello,

I have a N9342C Handheld Spectrum Analyzer and cannot read out trace data from MATLAB using VISA-USB.

I can control the instrument fine (change modes, configure values, trigger measurements), but when I use the command from the programmers guide to request the trace data ('TRACe1?'), I get a '-109,Missing parameter' error on the HSA screen and there is no data in the buffer to read in. I have tried using the full 'TRACe1:DATA?' and get the same error. I have also tried adding in parameters but it just leads to other errors ('-128,Numeric data not allowed', '-113,Undefined header').

Am I missing something obvious or does anybody have any advice?

Thank you,
RW
