Abstract: This application note helps system designers choose the correct external components for use with the MAX16948 dualremote antenna LDO/switch, thus ensuring that automobile-regulated phantom antenna supply and output-current-monitoring circuitrymeet performance objectives. An electronic calculator is provided that helps specify the critical external components for theMAX16948, thus reducing design time. The calculator also determines the device's analog output voltage, output current-limitthreshold, and output current-sensing accuracies. The calculator includes new automatic Step By Step feature that assists designerswith component choice. To use the new automatic feature, click on the Step By Step button relative to the desired section.

pkpm2005破解版安裝方式: 一、Windows XP下PKPM的安裝方法: 1. 先安裝正版的 PKPM 。 2. 將本機的 system32\WinSCard.DLL 改名為 SysCard.DLL 。 3. 將本破解包里的 WinSCard.INI 復制到 C: 盤根目錄。 4. 將本破解包里的 WinSCard.DLL 復制到系統system32目錄。 5. 將本破解包里的 WinSCard.DLL 復制到pkpm里各模塊目錄下。 二、Win 7下PKPM的安裝方法: 1.解壓后有兩個文件夾:(PKPM2005.12.17)和(PKPM2005.12.17綜合破解方案) 先打開前一個文件夾安裝正版的 PKPM 。 2. 打開后一個文件夾將本機的 system32\WinSCard.DLL 改名為 SysCard.DLL 。 3. 將本破解包里的 WinSCard.INI 復制到 C: 盤根目錄。 4. 將本破解包里的 WinSCard.DLL 復制到系統system32目錄。 5. 將本破解包里的 WinSCard.DLL 復制到pkpm里各模塊目錄下(就是安裝好的程序中的所有文件夾)。 6。還有WinSCard.INI 復制到 C: 盤根目錄需要在安全模式下進行。 注意:(windows7中修改系統文件需要獲得TrustedInstaller權限,具體修改方法:在WINDOWS7下要刪除某些文件或文件夾時提示“您需要TrustedInstaller提供的權限才能對此文件進行更改”,這種情況是因為我們在登陸系統時的管理員用戶名無此文件的管理權限,而此文件的管理權限是“TrustedInstaller”這個用戶,在控制面板的用戶管理里面是看不到的。要想對這個文件或文件夾進行操作,可以用以下方法進行:在此文件或文件夾上點右鍵,選“屬性”→“安全”,這時在“組或用戶名”欄可以看到一個“TrustedInstaller”用戶名,而登陸系統的管理員用戶名沒有此文件的“完全控制”權限,這時我們可以選擇“高級”→“所有者”→“編輯”,在“將所有者更改為”欄中選擇登陸系統的管理員用戶名,然后點“應用”,這時出現“如果您剛獲得此對象的所有權,在查看或更改權限之前,您將需關閉并重新打開此對象的屬性”對話框,點“確定”,再點兩個“確定”,在“安全”對話框中選“編輯”,出現了該文件或文件夾“的權限”對話框,在上面的欄中選中登陸系統的管理員用戶名,在下面的欄中選擇全部“允許”,然后點“應用”,再點兩個“確定”,這時你就可以擁有該文件或文件夾的更改權限了。) 這里有兩份破解包,雖然有些文件相同,但針對不同用戶,可能一個包不能破解,所以推出兩包破解綜合方案,這兩個包文件名分別為:pkpmcr1.rar和pkpmcr2.rar,下載后,分別解壓,先運行pkpmcr1.rar中的setup.bat文件,如果提示:“一個文件正在使用,已復制0個文件。”并運行PKPM后發現未能破解,請將pkpmcr2.rar包中WinSCard.DLL文件復制到PKPM各模塊所在文件夾中,即可完成破解,本站試用過結構、建筑、鋼結構三個模塊,均可用,如需應用到工程實際中,請與正版對比后,斟酌使用,謝謝。本站對其未對比就使用此破解版導致的不良后果,不負責任,切記。本貼已關閉,有事請在本版開新貼說明。 這是PKPM2005.12.17版綜合破解方案的第二包,文件名是pkpmcr2.rar,應用請遵循第一貼的說明,這二個包是有區別的,雖然文件名和大小及其屬性相同,但還是有區別的,請看兩個包中的說明文件,如果包1未能成功破解,請用包2,謝謝. 這里FTP里有以下軟件可以下載用戶名xudown密碼down ftp://219.153.14.92/APM2005.exe ftp://219.153.14.92/PKPM2005.12.17.rar ftp://219.153.14.92/比較工具.exe ftp://219.153.14.92/橋梁通安裝狗.exe ftp://219.153.14.92/正版鎖計算模型的結果.rar
