6 | GPIB and parallel interface (Option A4H) is an optional interface. GPIB |
| supports remote analyzer operation. A parallel port is included for printing |
| only. |
7 | |
| supports remote analyzer operation. A parallel port is included for printing |
| only. |
|
|
NOTE | Printing is only supported from the parallel port. |

|
8 | 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 |
| conversion) proportional to vertical deflection of the trace. Output is from 0 |
| V to 1 V. |
| AUX IF OUT is a 50 Ω , 21.4 MHz IF output that is the |
| of the RF input of the analyzer. |
| 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. |
|
|
9 | FM Demod (Option BAA) demodulates, displays, and measures deviation on |
| FM signals. You can listen to audio signals on a |
| 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. |
10 | Frequency Extension Assembly controls the microwave |
| components in the Agilent E4404B, E4405B, E4407B, and E4408B. |
