Agilent Technologies E1439 manual Agilent Technologies Sales Office, Front panel data port

Glossary

anti-alias filter	An analog low pass filter inserted the signal path to eliminate
	undesirable frequency components which appear under the alias
	of another (baseband) frequency. For more information, see
	Spectrum and Network Measurements available through your
	Agilent Technologies Sales Office.
baseband	A band in the frequency spectrum that begins at zero. In contrast
	a zoomed band is centered on a specific center frequency.
block mode	A mode in which the Agilent E1439 stops taking data as soon as a
	block of data has been collected.
block size	The number of sample points in a block of data. For complex
	data, block size is the number of complex data pairs per data
	block.
BOF	A fiber frame that acts as a synchronizing event.
continuous mode	A mode in which the Agilent E1439 collects data continuously. It
	does not stop taking data unless the FIFO overflows.
data frames	A fiber frame that contains 0 to 512 32-bit data words.
decimation filter	A digital filter that simultaneously decreases the bandwidth of the
	signal and decreases the sample rate. The digital filter provides
	alias protection and increases frequency resolution. For more
	information, see Spectrum and Network Measurements available
	through your Agilent Technologies Sales Office.
EOE	A fiber frame that contains the last 4 data bytes in an epoch.
epoch	One or more data frame followed by an EOE.
fiber frame	A series of 32-bit values that can either be data or an ordered set.
FIFO	A First In, First Out buffer and controller used to transmit data.
FPDP	Front panel data port.
LO	Local oscillator
VCXO	Voltage controlled crystal oscillator
zoom	Selects a frequency span around a specified center frequency. This
	is also known as band selectable operation.
