TRIGGER MENU | OPERATION |
| The Trigger function in the ML2430A allows the user to define under what condi- |
| tions measurements are taken, and the time period they are taken over. For in- |
| stance, the READOUT mode can be configured to display the average power of |
| the ON period of a square wave, or an individual slot in a GSM burst. |
| The Trigger menus are always available in PROFILE operation mode, as selected |
| from the System menu. If PROFILE cannot be selected within the SystemSetup |
| submenu, change the GPIB mode to ML24XX in the SystemRear Panel |
| submenu. |
| In READOUT or POWER vs. TIME modes, the trigger setup menus are available |
| if the channel input configuration SENSORSetupMODE is set to CUSTOM. A |
| display channel using more than one sensor |
| sor is in CUSTOM mode, is assumed to be in custom mode and can use trigger- |
| ing. Trigger setup is available only for the display channels that meet the above |
| criteria. |
| In PROFILE mode, the display shows an ‘x’ marking the trigger point plus the dis- |
| play trigger delay time, updated for each new set of data. This trigger point mark |
| rotates as the profile data is updated, changing between '' and '+' on each data |
| update. On rapid updates, the trigger point mark may appear like a star (), as it |
| is rotating so quickly. In manual, external or GPIB triggered displays, the mark ro- |
| tates at a slower rate and each true data update can be seen. |
| This point can be moved across the x axis by the pre trigger percentage. If the |
| trigger source is either default, mod average or custom continuous, the trigger |
| point has no meaning since the system is continuously triggering. The mark does |
| not appear in the Power vs. Time or Source Sweep modes, as it is not applicable. |
| Trigger icons indicate the type of triggering selected and appear level with the re- |
| lated channel on the far left of the screen. Trigger icons are not displayed if the |
| system is in Profile, Power vs. Time, or Source Sweep operation modes, if all |
| sensors used in a channel input configuration are in the DEFAULT measurement |
| mode, or if the peakmeter is displayed. |
| NOTE |
| When editing an entry in a menu, pressing the CLR key |
| clears the digits. If in a menu screen, pressing the CLR key |
| returns to the previous menu level. |
