Operation 4-4
4.4 Data Entry Controls
The numeric keypad illustrated in Figure 4-6 is one of the three data entry controls that enable you to enter parameters for the
various control functions. The keypad is subdivided into three areas: numerals, units of measure and controls. The ten
numerals, the minus sign and the decimal point are used to enter numerical data. Six ―units of measure‖ keys are provided for
you to use to complete numerical entries. When entering time intervals, press the ―m‖ after entering the numbers to indicate
milliseconds or milliseconds/division; press ―u‖ to indicate microseconds or microseconds/division; and press ―n‖ to indicate
nanoseconds or nanoseconds/division. Press ENT to indicate seconds or seconds/division. Pressing any one of these ―units‖
keys enters the numerical data.
When entering numbers that are not time intervals (dBm for example), press the ENT key after keying the number. Pressing
one of the units keys after entering a non-time-related number has the same effect as pressing ENT.
