In the de fault con fig u ra tion, the An a log Gen er a tor panel is set for a 1 Vrms,
1 kHz sine wave, but the an a log out puts are dis abled. To turn on the out puts,
click the OUTPUTS OFF but ton near the cen ter of the panel. The but ton will
turn green, and you will hear re lays click in the in stru ment hard ware. The
Level me ters on the An a log An a lyzer panel will show ap prox i mately 1.000 V.
The Level me ters show the rms level of the sig nals at the an a log in puts.
The ste reo An a log Gen er a tor out puts can be in di vid u ally dis abled with the
CHA and CHB but tons next to the OUTPUTS field. Click on the CHB but -
ton. The but ton will turn gray, re lays will click in the in stru ment, and the
Chan nel B Level me ter on the An a log An a lyzer panel will in di cate a level of
0.000 V.
Now that we’ve suc cess fully routed a sig nal from the An a log Gen er a tor to
the An a log An a lyzer, we will perform some ba sic mea sure ments.

The 2700 se ries has two in de pend ent gen eral-pur pose an a lyz ers that can

The An a log An a lyzer is an an a log-do main real-time au dio an a lyzer, im ple -

At this point, you should have the setup shown in Fig ure 19:
