Alarm Enable —
When Enable is selected, alarms will be reported whenever
signal conditions exceed alarm settings.
Options are Enabled and Disabled.
VSWR Trip Point —
Selectable set point for VSWR alarm, Settings are 1.3
through 2.5.
An alarm is triggered when:
If VSWR is equal to or slightly higher than the trip point, reflected
power is monitored for trend.
If reflected power is increasing an alarm is triggered.
If reflected power is not increasing, and VSWR exceeds trip point
for 30 seconds an alarm is triggered.
If VSWR is much greater that the trip point an alarm is triggered
immediately.
Low Power Alarm Enable —
When Low Power Alarm AND Alarm Enable are
enabled, alarms will be reported whenever signal conditions fall below alarm
settings.
Options are Enabled and Disabled.
Low Power Alarm Level —
Setting for the trip point for the low power
alarm. Enter the low power level for the alarm then select the unit associated
with the value.
High Power Alarm Enable —
When High Power Alarm AND Alarm Enable
are enabled, alarms will be reported whenever signal conditions exceed alarm
settings.
Options are Enabled and Disabled.
High Power Alarm Level —
Setting for the trip point for the high power
alarm. Enter the high power level for the alarm then select the unit associated
with the value.
Forward DAC Gain —
The BPME has an linear analog output voltage of 0-2
VDC representing the full scale of the forward power. The Forward DAC Gain
setting allows the adjustment of the value the voltage represents. This allows for
increased resolution at lower power levels.
1 - 2 VDC = Full Power
2 - 2 VDC = 1/2 Full Power
4 - 2 VDC = 1/4 Full Power
8 - 2 VDC = 1/8 Full Power
Note:
If the full scale of the BPME is 2.5 W to 250 W.
If 1 is selected for the DAC Gain the 2 VDC output would be the
equivalent of 250 W.
If 2 is selected for the DAC Gain the 2 VDC output would be equivalent
of 125 W.
