Data Description
Code
When setting the bias/gain (instruction
H6C
codes H5E to H61, HDE to HE1) parame-
ters:
H00: Frequency
H01: Parameter-set analog value (%)
H02: Analog value input from terminal
HEC
The gain frequency can also be written
using Pr. 125 (instruction code H99) or
Pr. 126 (instruction code H9A).
