Detailed Operation

3.3.2.10 Shake

The SHAKE mode performs repetitive mount movements. The SHAKE mode is for support of mount testing and for automatic mount demonstrations such as trade shows. The SHAKE mode is only available if expert access is enabled.

The SHAKE mode implements a repetitive sequence of three “moves”. Each “move” is programmed with azimuth, elevation and polarization targets. Moves # 1 and 2 proceed in the order elevation, polarization and azimuth. Move # 3 proceeds in the order of azimuth, polarization and elevation to accommodate a “stow-like” sequence. NOTE: if polarization movement is not desired, set the polarization type (see polarization configuration) to “circular”. When SHAKE is selected, the following screen appears.

This opening screen shows the programmed values for the SHAKE mode. The azimuth(AZ), elevation(EL) and polarization(PL) targets for each of the three “moves” is displayed. Also displayed is the programmed number of movement CYCLES to accomplish and the time in seconds to DELAY between each “move”. The pattern the above move targets describe is shown in the following figure.

The programming of the targets, cycles and delay is accomplished via the SHAKE configuration screen (3.3.1.17). To initiate the SHAKE sequence, press the Pol CCW/1 key. If you wish to modify the SHAKE parameters go to the CONFIG-SHAKE mode. To exit out of SHAKE press the Mode key.

When SHAKE is started the following screen appears:

AZIM:

0.2

SHAKE

ELEV: -55.3

POL:

CYCLE:

<STOP>HALT

MOTION <MODE>MAINT

 

As each axis moves its header (AZIM, ELEV, POL) flashes and the current position is updated. The CYCLE field shows the current_cycle / total_cycles . When the SHAKE function is delaying between moves, "DELAY” is displayed.

Movement may be stopped at any time by pressing the Stop or Mode keys.
