<h3><span lang=EN-US>Switchover to Remote Control</span></h3>

<p><span lang=EN-US>On power-up, the instrument is always in the manual 
 operating state and can be operated via the</span><span lang=EN-US
														style="x-condition: ZVB_A;"> 
 front panel controls</span><span lang=EN-US>. 
 The instrument is switched to remote control as soon as it receives a 
 command from the controller.&nbsp;If the instrument is controlled via 
 RSIB or VX 11 interface, the alternative commands </span><span lang=EN-US
	style="font-style: italic;"><I>@REM</I></span><span lang=EN-US> and </span><span 
 lang=EN-US
	style="font-style: italic;"><I>@LOC</I></span><span lang=EN-US> can be used 
 to switch from manual to remote control and back. </span></p>

<p class=InlineNormal8>While remote control is active, operation via the 
 front panel is disabled with the exception of two softkeys. The instrument 
 settings are optimized for maximum measurement speed; the display is switched 
 off: </p>

<p class=Figure><img src="Remote_screen_empty.gif" width="587px" height="309px" border="0" class="img_whs1"></p>

<p>The two softkeys in the remote screen are used to modify or quit the 
 remote state: </p>

<ul>
	
	<li class=kadov-p-Clist><p class=list><span style="font-style: italic;"><I>Go

<div class="droptext" id="POPUP259005603" style="display: 'none'; " x-ss-type="dropdown">
 <p>Switching on the display means that the analyzer shows the measurement 
 screen with the current setups, diagram areas and traces without leaving 
 the remote state. In this operating mode, it is possible to observe the 
 screen while a remote control script is executed and the control elements 
 on the front panel are still disabled: </p>
 <p class=Figure><img src="Remote_screen.jpg" width="595px" height="333px" border="0" class="img_whs3"></p>
 <p>Switching on the display is ideal for program test purposes but tends 
 to slow down the measurement. Therefore it is recommended to switch off 
 the display in real measurement applications where a tested program script 
 is to be executed repeatedly. </p>
 <p><img src="../../small_images/tip.jpg" x-maintain-ratio="TRUE" width="36px" height="37px" border="0" class="img_whs4"> The analyzer provides a third display option where the 
 measurement screen is only updated when this is triggered by a remote
