GPIB and parallel interface (Option A4H) is an optional interface. GPIB

 

supports remote analyzer operation. A parallel port is included for printing

 

only.

7

RS-232 and parallel interface (Option 1AX) is an optional interface. RS-232

 

supports remote analyzer operation. A parallel port is included for printing

 

only.

 

 

NOTE

Printing is only supported from the parallel port.

IF, Video, and Sweep Ports (Option A4J or Option AYX): (Refer to the

 

specifications guide for more information.)

 

SWP OUT provides a voltage ramp corresponding to the sweep of the

 

analyzer (0 V to 10 V).

 

HI SWP IN (TTL) can be grounded to stop and reset the sweep. Once the sweep

 

has been stopped, removing the ground will trigger the start of a new sweep.

 

HI SWP OUT (TTL) is high when the analyzer is sweeping.

 

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.

 

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.

 

NOTE Only one IF and Sweep Port option (Option A4J or Option AYX) can be installed at

 

a time.

FM Demod (Option BAA) demodulates, displays, and measures deviation on

 

FM signals. You can listen to audio signals on a built-in speaker or with an

 

earphone. Refer to “Det/Demod” and “FM Demodulation (Option BAA)” in the

 

Options chapter for more information.

 

Bluetooth FM Demodulation (Option 106) demodulates, displays and measures

 

deviation on Bluetooth signals. Refer to “Det/Demod” and “Bluetooth FM

 

Demodulation (Option 106)” in the Options chapter for more information.

Frequency Extension Assembly controls the microwave front-end

 

components in the Agilent E4404B, E4405B, E4407B, and E4408B.
