Rear Panel Description

5. TRIGGER IN The external trigger allows external triggering of

		measurements. The external trigger accepts an
		external trigger signal between −5 and +5 V, and has a
		nominal impedance of 10k Ω. For more information on
		triggering, see page 85.
	6. SCSI	Currently the SCSI connection can only be used to
		connect an external SCSI drive for firmware upgrades.
		SCSI functionality will be fully implemented with a
		future firmware update.
	7. Line Power Input AC power line connection. The line voltage operates
		at nominally 115 V (47 to 440 Hz) or at nominally 230 V
		(47 H to 66 Hz). The input power ranges for the power
		supply are 90 to 132 V or 195 to 250 Vrms. The power
		supply automatically senses the input power and
		switches between these two ranges. There is no
		customer replaceable power fuse. When on, the
		instrument consumes less than 350 W; when in standby
		less than 20 W.
	8. KYBD	This feature is not implemented. This feature will be
		implemented with a future firmware update. The KYBD
		enables connection of an external PS-2 keyboard using
		a 6-pin mini-DIN connector. If no keyboard is available
		you can use the numeric keyboard and the Alpha Editor
		menu key feature to make the entries. The keyboard
		must be plugged into the instrument prior to powering
		the instrument on or the keyboard will not work.
	9. GPIB	The GPIB allows the connection of a General Purpose
		Interface Bus (GPIB) cable, which enables remote
		instrument operation.
	10. LAN-TP	The LAN-TPconnector can be used:
		- as a SICL server emulating IEEE 488.2 protocol
		over LAN.
		- for a telnet programming port that can be sent
		SCPI commands.
		- for a TCP/IP socket programming port that can be
		sent SCPI commands.
		- for anonymous FTP operations to retrieve a screen
		“gif” or screen “xwd” file from the ftp/pub.
