The instrument has a counter input that can act as a frequency meter. When fed with a 10 MHz signal (from its own 10 MHz reference), the measurement on the instrument display is a stable
10.000 000 000 0 MHz
(10 digits after the decimal separator). However, when reading the counter using SCPI command ":COUNter:MEASure?", the SCPI response is a number in engineering format showing a different value:
9.999 999 975 E+06
Same problem reading other numbers, for example the frequency set for channel 2 of the generator. On the screen is "123.123 456 789 kHz", but when reading it by SCPI it is shown as "1.231 235 E+05". In the pics the SCPI commands were sent using LXI Tools/LAN/Ubuntu. With other tools (e.g. using netcat instead of LXI Tools) the results are the same, it's the instrument that sends the numbers in engineering format and with less decimals than displayed.
1. Is this a common issue for SCPI readings, or is it something specific to this instrument?
2. Any idea how to read by SCPI the full numbers, with all the decimals shown on the instrument's display?
