OPERATION SYSTEM MENU

NOTE

For the power meter to communi- cate with Anritsu 68/69000-series synthesizers using Source IF, the synthesizer firmware must be later than the levels shown for the vari- ous models below:

Model - firmware level 680xxB - 3.39 681xxB - 3.44 682xxB - 2.41 683xxB - 2.50 680x5B - 1.26 681x5B - 1.32 682x5B - 1.30 683x5B - 1.34 690xxA - 1.21 691xxA - 1.26 692xxA - 1.26 693xxA - 1.35 690x5A - 1.21 691x5A - 1.24 692x5A - 1.24 693x5A - 1.31

Contact your nearest Anritsu Ser- vice Center for a firmware upgrade if necessary.

Source IF allows the power meter to communicate with an Anritsu 68/69000-series synthesizer when the operation mode is set to Source Sweep.

BAUD [RSBAUD]

Sets the serial port BAUD rate. Select from 1200, 2400, 4800, 9600 (default), 19200, or 38400. The other RS232 serial parameters are fixed at 8 bits, 1 stop bit, and no parity.

MODEM

This menu controls how a modem will react when the power meter attempts to connect to a remote computer. It allows entry of a PHONE number, redial COUNT and redial DELAY, and permits IN- ITialisation of a connected modem.

PHONE number [MODPH] – The phone number can be up to 40 digits. When the number is being dialed, a dot (.) will be inter- preted as a 2-second delay in the dialing sequence; a minus sign

(–) will be interpreted as wait for another dialing tone.

Redial COUNT [MODRED] – If the dialed number does not con- nect, because it was not answered or was engaged, then the power meter will try to redial the same number according to the count specified. This has a minimum value of 0, maximum value of 10 and default value of 5.

Redial DELAY [MODDEL] – If the dialed number does not connect, and is to be redialed, this value specifies the delay in minutes be- fore redialing. This has a minimum value of 1 minute, maximum value of 10 minutes and a default value of 5 minutes.

INITialize Modem [MODINIT] – This is a single shot command to reinitialize a connected modem. As at power on, if this command is executed with a PC connected directly to the power meter, then a string of modem commands will be seen by the PC.

AUTO

Sets up the power meter to autodial if there is a LIMITS test failure, sensor RANGE error, or the instrument POWER is cycled.

LIMITS [MODLIM] – If this is set, and the limits fail, then the num- ber specified in the “phone number” field will be dialed. Remote communications can then continue as normal.

RANGE [MODRNG] – If this is set, and there is a signal channel range error, then the number specified in the “phone number” field will be dialed. Remote communications can then continue as normal.
