Units Min Max
dBm -270 220
dBmV-53.00 147.00
dBV 7.00 207.00
Watts 0.0 50.0
Remarks: Sets the high limit. The HLIMS command turns the limits on and off. It
is not necessary to enter the units as the limit value is checked against
the displayed value. Therefore, if the limits have been set for –10 dBm
(HLIM 1, –10) and the display units are subsequently changed from
dBm to Watts, the system will still check for the reading to rise above
-10, even though the display units type has been changed.
Example: The high limit is set to –10 dBm and turned ON. The display is in dBm.
A reading of –9.500 dBm would pass. If the display is subsequently
changed to Watts, a reading of 112.2 mW would fail, because the
DISPLAYED value is higher than –10. Limit checking only uses the
displayed value and does not change its value even though the display
units have changed.
