Control Fields on the Configuration Screens

Date

This field specifies the current date for the internal clock. The date can be read by a controller using GPIB and printed on test results.

The format is MMDDYY (Month Day Year), using two digits for each term. When entering months January through September (01-09), the leading zero is not displayed when entered. Example; May 5, 1993 is entered as 050593, but is displayed as 50593.

The internal clock still functions when the instrument is turned off.

Duplex Out

This field is used to indicate losses or gains between the DUPLEX OUT port and the device-under-test.

•Enter a positive value to indicate a gain (such as an amplifier gain). The RF generator’s level is automatically set that amount below what is indicated in the RF generator’s Amplitude field. (Example; if

this value is 10 dB, and the Amplitude field shows 0 dBm, the actual level out this port is − 10 dBm.) The value at the output of the external amplifier should then be at the level indicated in the

Amplitude field.

•Enter a negative value to indicate a loss (such as cable loss). The RF generator’s level is automatically set that amount above what is indicated in the RF generator’s Amplitude field to compensate. The value at the opposite end of the cable (loss) should then be at the level indicated in the Amplitude field; unless the resulting RF generator setting exceeds the maximum output level, then an error occurs: Input value out of range. In that case, reduce the Amplitude setting, or decrease the Duplex Out value.

This field is only used when the RF Level Offset field is set to On.
