Anritsu FAQs

The Sitemaster and the Handheld Software Tools program (HHST) will work with almost any commercially available USB to Serial adapter. If you don't have one yet, you can order one from us (P/N 551-1691) or pick one up from almost any electronics parts store (Fry's, Radio Shack, etc). You will have to install the drivers that come with the device and then go into control panel on your PC and manually set the Com port to Com 1 through Com 6, as these are the only ports our program will operate on. In Windows XP, you can do this by going to Control Panel, System, Hardware, Device Manager, Ports, Communications Port, Port Settings, Advanced, then click on the Com port pull-down; and it will show you which Com ports are in use on your machine. Set it to an unused port number 1 through 5. Then check the Com port settings in our program under Settings/Communication. It should match the port you have selected in Control Panel. Set the baud rate to 38,400 as this is the common rate limitation of most USB to serial adapters. After you get your setup working, you can experiment with higher baud rates if you wish. Note that newer units such as the D models can support higher transfer speeds than the older A and B models. You should also be using the latest version of Handheld Software Tools, which can be found by entering the term HHST in the search box on our website (www.us.anritsu.com). Sometimes it is useful to perform a Factory Default reset on the Sitemaster after trying unsuccessfully to communicate wit h it. This can be done by holding the Escape key in the upper righthand corner of the keypad while pressing the On/Off switch to turn the unit on. This will reset the unit but not affect any of the saved sweeps on it or the memory in any way. It simply helps to "clear the cobwebs" out of the unit.
