Up/Down Pattern

Choice: Custom Pattern | User File | External

Default: External

Select the transmission power control up/down pattern.

External

Sets the Transmission Power Control (TPC) data pattern to External. This choice specifies an external TPC pattern.

Custom Pattern

(PATTern)

Sets the Transmission Power Control (TPC) data pattern to Custom Pattern. The value of this command is a string which is represented ‘0’ or ‘1’. The maximum data length is 3,840 patterns.

User File

("<filename>")

This selection specifies a data pattern that has been stored in memory.

Edit the Up/Down Pattern by clicking on the cell. Then click on the dialog box icon to launch theClosedUp/Down Pattern dialog box.

When loading a user file through the software's Data dialog box, the MXG/EXG requires an ASCII text file consisting of 1s and 0s. When using SCPI commands, all instruments require a binary data file.
