Rear-Panel Features
AUX VIDEO OUT provides detected video output (before
the analog-to-digital conversion) proportional to
vertical deflection of the trace. Output is from 0 V to
1 V. Amplitude-correction factors are not applied to this
signal.
The output signal is blanked during retrace.
AUX IF OUT is a 50 Ω, 21.4 MHz IF output that is the
down-converted signal of the RF input of the analyzer.
Amplitude-correction factors are not applied to this
signal. This output is taken after the resolution
bandwidth filters and step gains and before the log
amplifier. The output signal is blanked during retrace.
9 FM Demod (Option BAA) allows you to demodulate,
display, and measure deviation on FM signals. You can
listen to audio signals on a built-in speaker or with an
earphone. Refer to “Det/Demod” in Chapter 6 and “FM
Demodulation (Option BAA)” in Chapter 7 for more
information about this option.
10 Frequency Extension Assembly controls the
microwave front-end components in the Agilent
E4404B, E4405B, E4407B and E4408B.
PRESEL TUNE OUTPUT provides a signal to control
external preselected mixers (Option AYZ). Refer to
“Det/Demod” in Chapter 6 or “FM Demodulation
(Option BAA)” in Chapter 7 for more information about
this option.
11 Card Slot Identification Numbers. Refer to Table
2-1 and Table 2-2 for card slot versus option card
compatibility information.
12 10 MHz REF IN accepts an external frequency source to
provide the 10 MHz, −15 to +10 dBm as a timebase.
13 10 MHz REF OUT provides a 10 MHz, 0 dBm minimum,
timebase reference signal.
14 Power On Selection selects an instrument power
preference. The
PWR ALWAYS ON setting turns the
analyzer on whenever external power is applied. This
mode is useful if an external power switch is used to
control a rack of several instruments. The
PWR NORM
setting assigns analyzer on/off control to the
front-panel On key (see Figure 2-1 on page 2-3, item
23); however, if the external power is removed for >20
seconds, the instrument returns to the Standby
condition of the front-panel On key when external
power is reconnected.
