• Value of r
Sets reference peak to r number at REL (Relative) display
r = 1 to 128
• Value of s
Sets whether the detected noise value should be normalized with the effective
resolution.
s = "ON"
= "OFF"
■ Response Data
m indicates the display mode as follows:
m = MPK: Multi Peak display
= SNR: SNR display
= REL: Relative display
Refer to the send data items for n, s, ∆λ, and r.
