* Specifications listed below are for the 4145A only.
For 16058A specifications, refer to
the 16058A Operation Note.
GENERAL INFORMATION
Basic Functions
: Measures the DC current through voltage-biased devices and the
DC voltage across current-biased devices; Arithmetic calculation; Displays
measurement results and calculation results on a built-in CRT display; graphics
analysis capabilities; storage and recall of measurement setups, measurement data,
and auto-sequence programs.
c
Source and Measurement Units :
Stimulus/Measurement Units (SMU) : Four SMU channels. Each SMU can be
programmed to function as a variable or constant DC voltage source/current
monitor or as a variable or constant DC current source/voltage monitor.
Voltage Sources (Vs) : Two Vs channels.
Each Vs c?an be programmed to
function as a variable or constant DC voltage source.
Voltage Monitors (Vm) : Two Vm channels. Each Vm can measure DC
voltages up to +2OV.
^I SOURCE/MEASUREMENT FUNCTIONS
Measurement and output accuracies are specified at 23 O +5 OC after the
instrument has been allowed to warm up for at least 40 minutes, with AUTO CAL
set to ON, INTEG TIME set to SHORT and referenced to SMU common. Specified
accuracy doubles for operation between 10 O C and 40 ' C.
Stimulus/Measurements Units (SMU) : Four SMU channels. Each SMU measures
current when operating as a voltage source, or measures voltage when operating as
a current source. Source and measurement ranges, resolution, and accuracy
specifications are given in the tables below.
Accuracy specifications in the below tables are given as +n% of specified output or
measured value, +n% of range value. 10 is output current (I), Vo is output voltage
