All plot files are kept in directories. There is one directory for each week. To choose a new plot to
view, use the selections on the right side of the page. First, click to select a directory. Then you can
either click to select one of the listed plot files, or you can use your mouse to hover over one of the
plot files. Hovering over a plot file will display a small plot next to the large main plot. In this way
you can compare plots from different types to correlate data. For example, you can compare an NTP
data plot with a CPU data plot.
Plots files can also be downloaded from the Sonoma as .PNG files. They can be found in the direc-
tory

Receiver: Receiver Page
This page contains information related to the CDMA Subsystem/Receiver. Data fields are:
CDMA Receiver Status
Subsystem State
This shows whether the current state of the CDMA Subsystem:
WRM:
Warmup period for units with oscillator upgrades.
ACQ:
Searching for a signal.
LKG:
Locking to the CDMA Signal.
LKD:
Locked. Fully synchronized to signal.
TFOM
The current TFOM value (see
Appendix A - TFOM
).
AGC
Automatic Gain Control DAC. Typical value is 150 to 220 in good signal
conditions.
SNR
Signal-to-Noise Ratio. Typical value is > 2.5.
FER
Frame Error Rate when decoding CDMA sync channel frames.
PNO
Pseudo-Noise Offset of the basestation.
Channel
This is the CDMA frequency channel being used.
Receiver DAC
This is the CDMA Receiver 16-bit DAC value.
Receiver State
This shows the current state of the CDMA Receiver:
WRM:
Warmup period for units with oscillator upgrades.
ACQ:
Searching for a signal.
DET:
A signal is detected.
LKG:
Locking to the Pseudonoise (PN) Code.
TRK:
Locking to the carrier.
LKD:
Locked. Fully synchronized to signal.
Configuration
Clock Calibration Clock Calibration is used to advance or retard the clock in order to correct for
propagation delay due to distance from the basestation. Calibration range is
±500,000 nanoseconds.
