Getting Acquainted with the Analyzer
N O T E
When using the knob to change frequency or amplitude settings, the trace data is shifted. Therefore, when using MAX HOLD A, MAX HOLD B , or MIN HOLD C , moving the center frequency with the knob will not simulate a drifting signal.
Number/Units Keypad The number/units keypad allows entry of exact values for many of the cable TV analyzer functions. You may include a decimal point in the number portion. lf not, the decimal point is placed at the end of the number.
Numeric entries must be terminated with a units key. The units keys change the active function in a manner prescribed by that function. For example, the units keys for frequency span are (GHz), m, m, and IHz], whereas the units for reference level are CWl,
If an entry from the number/units keypad does not coincide with an allowed function value (for example, that of a 12 MHz bandwidth], the cable TV analyzer defaults to the nearest allowable value.
Step KeysThe step keys allow discrete increases or decreases of the active function value. The step size depends upon the cable TV analyzer measurement range or on a preset amount. Each press results in a single step change. For those parameters with fixed values, the next value in a sequence is selected each time a step key is pressed. Changes are predictable and can be set for some functions.
