5.11.5 Operation
In normal operation the VFLM-70 configuration can be changed either
via its Front Panel menus or an external SNMP Manager. These
configuration parameters may be set only when the VFLM operating
mode is Idle. VFLM can be put into the Idle operating mode from the
front panel by disabling transmit or via SNMP. When the VFLM is set to
any other mode, the parameters are read-only. The status can be read
fron the front panel or external SNMP Manager regardless of the
transmit state.

SNMP Command
Description
Read Write
centerFrequency
Center frequency selection. The center frequency
ranges from 52 to 88 MHz. Resolution = 1 kHz.
X X
maxTxBandwidth
Indicates the maximum 25dB transmit bandwidth.
The chipsPerBit*dataRate*3*1.35 shall not be
allowed to exceed this level. Resolution = 100KHz.
Max allowable setting = 44MHz.
X X
OqpskBpsk
Sets the spread spectrum modulator up in either
OQPSK mode (default) or BPSK mode. 2 = QPSK, 1
= OQPSK, 0 = BPSK.
X X
dataRate
Data Rate in kbps from 500kbps to 10Mbps.
X
X
chipsPerBit
Chips per bit for PN Spreader (1 to 23)
X
X
uniqueWord Modulator
Unique Word (32-bit)
X
X
tapConfigurationWord
PN Spreader Used (16-bit). For a generator
polynomial the word is configured as g
16
, g
15
, … g
1
(g
0
=1 always).
X X
initialContentWord
PN Spreader Initial Setting (16-bit)
X
X
truncationCount
Count value for truncating the PN code. The value
must be a multiple of the chipsPerBit. If the value
is not a multiple, truncate to the nearest and echo
the value as an SNMP trap or response on the
menu. (max size 16-bits).
X X
txOutputPower
Desired modulator output power in dBm.
Resolution 0.1 dB. Range –25 to –5dBm.
X X
bufferSize
The maximum size is 2.048Mbits and the size
increments are 32 bits.
The value programmed is an integer from 1 to
64000. The value represents the number of 32 bit
increments, e.g. 64000x32 = 2.048Mbps
