Agilent Technologies E4438C manual General Characteristics, With Option UN7, LAN connector

General Characteristics

With Option UN7	Accepts CMOS 1 or 75 Ω input. Polarity is selected.
BER data, BER clock
BER gate	Clock duty and inputs cycle is 30% to 70%. [SMB, rear panel]
BER sync loss output	Outputs a CMOS1 signal that is low when sync is lost.
	Valid only when measure end signal is high. [Auxiliary I/O
	connector, rear panel]
BER no data output	Outputs a CMOS1 signal that is low when no data is detected.
	Valid only when measure end is high. [Auxiliary I/O
	connector, rear panel]
BER error-bit-output	Outputs CMOS1 signal when error bit is detected. Pulse width
	matches the input clock. [Auxiliary I/O connector, rear panel]
BER test result output	Outputs a CMOS1 signal that is high for fail and low for pass.
	Valid only on measure end signal falling edge. [Auxiliary I/O
	connector, rear panel]
BER measure	Outputs a CMOS 1 signal that is high during measurement.
end output	Trigger events are ignored while high. [Auxiliary I/O
	connector, rear panel]
BER measure trigger	Accepts CMOS1 signal to initiate BER measurement.
	Polarity is selectable; available when trigger source is
	selected as “AUX I/O”. Damage levels are The damage
	levels are –0.5 to +5.5 V. [Auxiliary I/O connector, rear panel]
With Option 300
321.4 MHz input	Accepts a 321.4 MHz IF signal for GSM/EDGE/loopback
	testing. Input amplitude range -7 dBm to -22 dBm.
	Nominal input impedance 50 ohms.

LAN connector

LAN communication is supported by the signal generator via the LAN connector. It is functionally equivalent to the GPIB connector. The LAN connector enables the signal generator to be remotely programmed by a LAN-connected computer. The distance between a computer and the signal generator is limited to 100 meters [10BaseT]. For more information about the LAN, refer to the Getting Started chapter in the Programming Guide.

Data transfer speeds2

LAN [SCPI]	command transfer to volatile memory	(146 KB/sec)
	to hard drive	(128 KB/sec)
Internal file transfer from hard drive to volatile memory		(1280 KB/sec)

Agilent’s IO Libraries Suite ships with the E4438C to help you quickly establish an error- free connection between your PC and instruments – regardless of the vendor. It provides robust instrument control and works with the software development environment you choose.

1.Rear panel inputs and outputs are 3.3 V CMOS, unless indicated otherwise. CMOS inputs will accept 5 V CMOS, 3 V CMOS, or TTL voltage levels.

2.Parentheses denote typical performance.
