The normal measurement estimates the power over the entire
channel. It multiplies the level at the center frequency of the
carrier by a scaling factor (determined from the bandwidth that
you have entered). The advantage of the normal measurement is
that it updates quickly.
The digiCheck™ measurement provides greater precision,
particularly when there is an irregular distribution of power over
the channel bandwidth. It takes measurements throughout the
selected bandwidth, summing the power across the entire
channel. Use digiCheck™ when you want maximum accuracy.
NOTE: The digiCheck™ measurement is
available only when you are using the LEVEL
mode. All other modes (e.g., SCAN, AUTO
TEST, etc.) perform the normal measurement
only.
Measurement Hold
You can freeze the level measurement at any time by pressing Shift
+ Snapshot keys. The measurement is retained even if the cable is
disconnected from the input port. Notice that the mode icon in the
upper left-hand portion of the screen flashes when the
measurement is on hold. Press Shift + Snapshot keys again to
release the hold. The hold is also released when you tune to a
different channel or frequency. The measurement is not retained
when another mode is selected or the MS1400 is shut off.
Printing The Screen
You can print the entire screen at any time by pressing Shift + Print
keys. A bar graph appears indicating the status of the printout.
TIP: If you are using your MS1400 at a
location were it is not convenient to connect to
a printer (such as on a pole), you can put the
measurement on hold until you are able to
access the printer.
Warning Indicators
If the current measurement is inaccurate due to an out-of-range
condition or a hardware failure, your MS1400 warns you by dimming
the numeric measurement value and displaying one of the following
warning indicators:
