ACPM or Output RF Spectrum Option (for GSM and GSM/GPRS only)
The Adjacent Channel Power Measurement (ACPM) Option provides the ETSI-
specified measurements on Output RF Spectrum, both due to modulation and
due to switching transients. Please refer to the 4400 data sheet for specifica-
tions. The measurements are explained in the sections about ACPM Modulation
Spectrum Measurements and ACPM Transient Spectrum Measurement, respec-
tively.
AM Signal Generator (for GSM and GSM/GPRS only)
The Amplitude Modulation (AM) Signal Generator is required by some manufac-
turers for testing and alignment of mobile phones. The functionality is explained
in the section about the non-call mode.

Operating the 4400 over a LAN with the TCP/IP Option
The 4478 TCP/IP Option allows you to connect the 4400 to a LAN. This method
has multiple benefits:
– It allows you to control the 4400 from an external PC (resolving the need for
a GPIB card in the PC).
– You can store result files on a remote PC from within your RAPID! applica-
tion or from the file manager (see sections “File menu” on page 137 and
“Commands for input/output handling” on page 178).
– You can access files on the 4400 from a remote PC (requires additional NFS
client software on the PC).
– You can speed up software updates and avoid bothering with floppy disks.
See section “Initiating a software update from a remote PC” on page 150.
The 4478 TCP/IP Option adds remote access capabilities to your 4400 from the
software side. The option includes an ethernet card to physically connect the
4400 to your LAN. This card can be plugged into the PCMCIA card slot of the
4400 and is fitted with a plug for an Ethernet connection (10 Base T).
