Note:
*1 AFLVLALL? command (which readouts all the measured results of the AF
Level) outputs the 8 types of the measured results, depending on the combi-
nation of the Filter and De-emphasis.
This command outputs the measured results of the ITU-T/750µs, C-MES-
SAGE/750µs, 6kHz BPF/750µs, Off/750µs, ITU-T/Off, C-MESSAGE/
Off, 6kHz BPF/Off, and Off/Off,in this order with commas for these data
separation.
Output format is shown below, where one data is indicated with 9 charac-
ters.
Example 1: Outputs with dBm unit. (Two digits under decimal point)
− − − − − −−− − −− − − − −−− − −−− − − −−− − −−−−−−−− − −−− − − −−− − −−−− − −−− − −−−− − −−− − −−−−−−−− −

Example 2: Outputs with Volt unit. (Exponent form)

*2 FREQCHAR? command (which readouts the measured results of the fre-
quency characteristics) performs FFT of the demodulated AF signal, and
outputs the frequency characteristics (from 50 Hz to 10 kHz,
in 50 Hz steps, with the reference of the data at 1 kHz).
When inputing this command, specify multiple integer values of n (range: 1
to 200) which are integer-type parameters to determine the measurement
frequencies.
The relation between n and the measurement frequency (f) is as follows:
f = 50n (n: 1 to 200)
