Subject: scpi-pps: adjust R&S HMP4000 current resolution for 10A channels
X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=7320ce5ecc5fbaac8cb43eda8fc0187812af27a8;p=libsigrok.git

scpi-pps: adjust R&S HMP4000 current resolution for 10A channels

Specs published by R&S suggest that 10A channels support 0.2mA resolution,
while only 5A channels resolve to 0.1mA (up to 1A full scale, 1mA above 1A).
