 <p>The two check boxes in the <span style="font-style: italic;"><I>Messages 
 and Sounds </I></span>panel switch the instrument messages or acoustic messages 
 on or off. Sounds are generated when the analyzer generates a notice/status 
 message or a warning (alarm sounds) or during calibration. The settings 
 are also valid if the instrument is remote-controlled. </p>
 <p><span style="font-style: italic;"><I>Dialog Transparency</I></span> varies 
 the transparency of all dialogs on a scale between 0% and 100%. 0% transparency 
 means that dialogs completely hide the diagram area in the background. 
 With a maximum transparency of 100%, the dialogs are still visible but 
 clearly show the underlying traces and display elements. </p>
 <p><span style="font-style: italic;"><I>Keep Measurement Data for &gt;Repeat 
 Cal&lt;</I></span> causes the raw measurement data of the standards to be 
 stored after the calibration is completed. This function is equivalent 
 to the parameter in the <span style="font-style: italic;"><I><a HREF="../Channel/Calibration/Guided_Calibration.htm#Measure_Standards"
	id=a44
	style="/*begin!kadov{{*/ position: relative; /*}}end!kadov*/ ">Measure 
 Standards</a></I></span>dialog of the calibration wizard (see detailed description there) 
 but applies to all calibrations. </p>
 <p><span style="font-style: italic;"><I>Automatic Power Reduction for Calibration 
 Unit </I></span>sets the source power at all test ports to &#8211;10 
 dBm while an <a HREF="../../System_Overview/Calibration/Automatic_Calibration.htm"

 calibration</a> 
 using the calibration unit R&amp;S ZV-Z51 or R&amp;S ZV-Z58 is active. 
 Applying this source power to the ports of the calibration unit ensures 
 best accuracy of the automatic calibration. The source power is reset 
 to its original value (e.g. the preset value of 0 dBm) after the calibration 
 is completed. The automatic power reduction can be deactivated in case 
 that the test setup introduces a large attenuation. &nbsp;</p>
 <p><span style="font-style: italic;"><I>No of Sliding Match Positions </I></span>defines 
 the maximum number of different positions to be measured if a sliding 
 match standard (sliding load) is used for calibration. The different positions 
 appear in the <span style="font-style: italic;"><I><a HREF="../Channel/Calibration/Guided_Calibration.htm#Measure_Standards"
													id=a82
													style="/*begin!kadov{{*/ position: relative; /*}}end!kadov*/ ">Measure 
 Standards</a></I></span>dialog of the calibration wizard. A sliding match calibration is 
 valid after three calibration sweeps at different match positions; however, 
 calibration sweeps at additional positions can still improve the accuracy. 
 In general 4 to 6 positions are recommended. </p>

 a user preset file. A user preset file is an arbitrary <A href="javascript:void(0);" onclick="BSSCPopup('System_Menu_text0.htm');return false;" onMouseOver="if (parseInt(navigator.appVersion) >= 4) BSPSPopupOnMouseOver(event);" class="popupspot" >setup</a>
