Chapter 2 Functions and Operations
AMPLITUDE | Displays the amplitude or scale menu depending on the measurement mode. |
Amplitude | Provides for changing the display scale. Selected values may be changed using |
Menu | the Up/Down arrow key or keypad. |
| Choosing AMPLITUDE in FREQ or DTF measurement modes causes the soft |
| keys, below, to be displayed and the corresponding values to be shown in the |
| message area. |
| TOP — Opens the top parameter for data entry and provides for setting the |
| top scale value. Press ENTER when data entry is complete. |
| BOTTOM — Opens the bottom parameter for data entry and provides for set- |
| ting the bottom scale value. Press ENTER when data entry is complete. |
| Choosing AMPLITUDE in SPECTRUM ANALYZER mode causes the soft keys, |
| below, to be displayed and the corresponding values to be shown in the message |
| area. |
| REF LEVEL — Activates the amplitude reference level function. |
| SCALE — Activates the scale function in a 2 through 15 dB logarithmic am- |
| plitude scale. |
| ATTEN — Sets the Anritsu input attenuator so that it is either coupled auto- |
| matically to the reference level (AUTO) or manually adjustable (MANUAL). |
| UNITS — Choose from the menu of amplitude related units. Selection of |
| dBm sets absolute decibels relative to 1 mW as the amplitude unit. Selection |
| of dBV, dBmV or dBV sets absolute decibels relative to 1 volt, 1 millivolt, |
| or 1 microvolt respectively as the amplitude unit. |
