Impedance Module

The Impedance Module corresponds to the Cal sub-tab in the LabOne User Interface Impedance Analyzer tab. It allows the user to perform a compensation that will be applied to impedance measurements.

Table 1. Impedance Module Parameters.
Setting/Path Type Unit Description

directory

string

-

The directory where files are saved.

calibrate

bool

-

If set to true will execute a compensation for the specified compensation condition.

device

string

-

Device string defining the device on which the compensation is performed.

step

int

-

Compensation step to be performed when calibrate indicator is set to true.

step=0

First load

step=1

Second load

step=2

Third load

step=3

Fourth load.

mode

int

-

Compensation mode to be used. Defines which load steps need to be compensated:

3:

SO (Short-Open)

4:

L (Load)

5:

SL (Short-Load)

6:

OL (Open-Load)

7:

SOL (Short-Open-Load)

8:

LLL (Load-Load-Load)

status

int

-

Bit coded field of the already compensated load conditions (bit 0 = first load).

loads/0/r

double

Ohm

Resistance value of first compensation load (SHORT).

loads/1/r

double

Ohm

Resistance value of second compensation load (OPEN).

loads/2/r

double

Ohm

Resistance value of third compensation load (LOAD).

loads/3/r

double

Ohm

Resistance value of the fourth compensation load (LOAD). This load setting is only used if high impedance load is enabled.

loads/0/c

double

F

Parallel capacitance of the first compensation load (SHORT).

loads/1/c

double

F

Parallel capacitance of the second compensation load (OPEN).

loads/2/c

double

F

Parallel capacitance of the third compensation load (LOAD).

loads/3/c

double

F

Parallel capacitance of the fourth compensation load (LOAD).

freq/start

double

Hz

Start frequency of compensation traces.

freq/stop

double

Hz

Stop frequency of compensation traces.

freq/samplecount

int

-

Number of samples of a compensation trace

highimpedanceload

bool

-

Enable a second high impedance load compensation for the low current ranges.

expectedstatus

int

-

Bit field of the load condition that the corresponds a full compensation. If status is equal the expected status the compensation is complete.

message

string

-

Message string containing information, warnings or error messages during compensation.

comment

string

-

Comment string that will be saved together with the compensation data.

validation

bool

-

Enable the validation of compensation data. If enabled the compensation is checked for too big deviation from specified load.

precision

int

-

Precision of the compensation. Will affect time of a compensation and reduces the noise on compensation traces, precision=0: Standard speed; precision=1: Low speed / high precision

todevice

bool

-

If enabled will automatically transfer compensation data to the persistent flash memory in case of a valid compensation.

progress

double

-

Progress of a compensation condition.
