13. SYST:READSTATE?[value]

The READSTATE query allows the user to read the parameters of the speciﬁed state without changing

any internal registers. The query output is a list of comma separated values, without spaces, in the fol-

lowing order: PLL mode, frequency, reference divider, reference internal/external, reference frequency,

max/min power setting, output power, RF power (on AR2010-4400 models only). See the respective

command deﬁnitions for descriptions of each parameter.

∙ 1 = FREQuency:PLLMode is set to integer (page 18)

∙ 8.000 = FREQuency:SET is set to 8 GHz (page 24)

∙ 2 = FREQuency:REFerence:DIVider is set to 2 (page 20)

∙ 0 = FREQuency:REFerence:EXTernal is set to internal (page 21)

∙ 20 = FREQuency:REFerence:FREQuency is set to 20 MHz (page 22)

∙ OFF = The string "OFF" denotes that neither "MAX" nor "MIN" has been speciﬁed as the output

power via the POWEr:SET command

∙ 0 = POWEr:SET is set to 0 dBm (page 27)
