Option E1962B-405 fading (digital bus)
Functionality
Allows baseband, digital I/Q data from the sig-
nal generator to be sent to an external N5106B
(PXB) and then returns the signal to the test set
for modulation
Connector
Rear panel, 50-pin, high density
Signal generator ALC
mode
Closed or open (default of closed); open loop
mode must be used during fading to maintain
the desired signal characteristics
ALC open loop
calibration
Calibrates the RF source when operating in the
ALC open loop mode; the accuracy remains
valid with a ± 5 °C window of the temperature at
which the calibration was performed
ALC open loop RF IN/ < ± 0.75 dB, −109 to –70 dBm/1.23 MHz
OUT composite absolute _{< ± 0.50 dB, –70 to −35 dBm/1.23 MHz}
output level
accuracy degradation
< ± 0.75 dB, −35 to −13 dBm/1.23 MHz
(must add this to the
main level accuracy
specification for tem-
peratures within ± 5 °C
of the last ALC open loop
calibration)
ALC open loop
carrier feedthrough
Typically < 40 dBc (nominal ambient < 47 dBc
after IQ calibration)
Option E1962B-406 multi-unit synchronization
Functionality
Allows any test set to be time-synchronized to
another test set running either CDMA or 1xEV-
DO test application or lab application; syn-
chronization requires one unit to be designated
as the time server and the other as the client;
timebase and trigger outputs of the server
must be connected to the client’s timebase and
trigger inputs; the test sets must also be on a
LAN using the same address segment
Sync to external test set One button command to perform the
synchronization
External test set LAN
address
User entry of the time server’s LAN address
(IPv4 address)
Synchronization fanout
Maximum of four client test sets can be driven
from a single timing server; unlimited number
can be synchronized when they are dai-
sy-chained together (one unit to another)
Synchronization results Server operation complete and client operation
complete
Synchronization
accuracy
Typically < 1 μs
Option E1962B-407 protocol logging
Functionality
Start protocol logging and stop protocol
logging
Protocol support
PREV=6 and PREV=7 messages; provides cor-
rect binary output for lower PREVs but decodes
using PREV=6 messages formats
