available for delta marker operation
Marker search:
Search type: max value, min value, multi-peak, multi-target, peak, peak left, peak right,
target, target left, target right, and width parameters with userdefined bandwidth
values
Search track: Performs search by each sweep
Search range: User definable
Other functions:
Marker continuous mode, Δ marker mode, Marker coupled mode, Marker value substi-
tution (Marker&), Marker zooming, Marker list, Marker statistics, and Marker signal/dc
bias monitor
Equivalent circuit analysis
Circuit models:
3-component model (4 models),
4-component model (3 models)
Analysis types:

Interface
GPIB
24-pin D-Sub (Type D-24), female; compatible with IEEE-488.
IEEE-488 interface specification is designed to be used in environment where electrical
noise is relatively low. LAN or USBTMC interface is recommended to use at the higher
electrical noise environment.
LAN interface
10/100/1000 Base T Ethernet, 8-pin configuration; auto selects between the two data
rates
