Section 1 : Turning On the AGILENT 35670A

The entire turn-on procedure for the AGILENT 35670A takes 40 seconds. In that time the analyzer completes a hardware self-test, boots its operating system, completes a front end self-calibration and autoranges all input channels. The default measurement state of the analyzer is a two-channel FFT measurement with a span of 51.2 kHz, front ends autoranging, input low floating, and DC coupled, averaging OFF and with a power spectrum display.
