IS-2000 test mode functionality
Cell 1 reverse link closed loop power control
transient
User start function that interrupts the current cell 1 reverse link
closed loop power control mode and substitutes the user-defined
number and direction of closed loop power control bits; once the
transient is sent, the closed loop power control reverts to the
original state
Cell 1 reverse link closed loop power control
transient modes
–– Up
–– Down
–– Up-down-up
Cell 1 transient number of steps
1 to 400
Cell 2 reverse link closed loop power control
modes
–– Alternating – alternating 0 and 1 power bits
–– Alt 20 up/down – alternating 20 up/20 down bits
–– All up
–– All down
–– Cell 1 bits – sets cell 2’s bits identical to cell 1’s
Forward link power support
None
Mobile station identification
User entry of ESN (hex); entry of all “F” hex data results in using a
zero long code mask on the source
F-FCH frame pattern
F-FCH frame pattern
Selectable repeating pattern of good, and corrupted frames with on
and off control
F-FCH/Traffic good and bad frame pattern Selectable on and off; “on” setting generates a pattern of good
frames and bad (corrupted) frames
F-FCH/Traffic frame pattern good frames Selectable from 1 to 300; default setting of 3 good frames
F-FCH/Traffic frame pattern bad frames
Selectable from 1 to 300; default setting of 3 bad (corrupted) frames
(50% FER)
Signaling frame quality
Selectable from good (ignores the F-FCH/Traffic frame pattern) or
bad (follows the F-FCH/Traffic frame pattern) for outer loop report;
when a report is received, the mobile reported set point is displayed
Option 004 Digital Bus
Functionality
Allows baseband, digital I/Q data from the signal generator to be
sent to an external N5101A Baseband Studio PCI card or N5106A
(PXB) for fading and then returned 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/out composite absolute
output level accuracy degradation (must add
this to the main level accuracy specification
for temperatures within ±5 °C of the last ALC
open loop calibration)
< ±0.75 dB, −109 to −70 dBm/1.23 MHz
< ±0.50 dB, −70 to −35 dBm/1.23 MHz
< ±0.75 dB, −35 to −13 dBm/1.23 MHz
ALC open loop RF OUT ONLY composite
absolute output level accuracy degradation
(must add this to the main level accuracy
specification)
< ±0.75 dB, −109 to −70 dBm/1.23 MHz
< ±0.50 dB, −70 to −35 dBm/1.23 MHz
< ±0.75 dB, −35 to −13 dBm/1.23 MHz
ALC open loop carrier feedthrough
Typically < 40 dBc, (nominal ambient < 47 dBc after IQ calibration)
