T_MODE, T_MODE? – Function Selection for the Trigger Inputs

Function

Two floating trigger inputs are provided at the analog interface,
whose action can be defined independent of each other. In this
way, control functions can be triggered at the device from the
application.
Depending upon which function is selected, the trigger input is
level or edge controlled.

Note

: Detailed descriptions of the control level are included in the

section entitled “Analog Interface”.

Setting Command

Syntax:

T MODE txt1,txt2

Default setting
or after RESET (*RST): OFF

Query Command

Syntax:

T MODE?

Sample response string:

T MODE txt1.txt2

Parameters List

The associated TRGx LED lights up along with the selected trigger input if the
trigger parameter is not set to OFF and the trigger input is active.

TSET, TSET? – Memory Location Specific Dwell Time for the
SEQUENCE Function

Function

The TSET setting parameter defines the memory location specific
dwell time for reading out a pair of voltage and current values for a
sequence. If no specific value, but rather 0 [s], is assigned to
TSET, TDEF is used as a default value for execution of the
sequence function.

Setting Command

Syntax:

TSET w

Value range:

0,000



65,535 [s]

Default setting
or after RESET (*RST): 0.000

Query Command

Syntax:

TSET?

Sample response string:

TSET w

Comments

If dwell times of greater than 65.535 seconds are required, this
can be achieved by specifying the same voltage and current
values for several consecutive memory locations.
Another possibility is to invoke subsequences with the
corresponding number of repetitions.

UI_C_SET, UI_C_SET? – Reference Values for Uout/Iout Tolerance Band Function

Attention!

While uploading the basic settings using the „write to de-
vice“ function in the „Notes“ tab of the Soft Front Panel
the saved parameters of the function „UI_C_SET“ will be
replaced by the current configuration.

Function

This function makes it possible to set up reference values for
voltage and current, which are continuously compared with
momentary measured values. In this way, for example, checking
is possible in order to determine whether or not actual voltage
and current values lie within the specified range (tolerance band
function). The results of this comparison can be queried in condi-
tion register CRB?, bits 0 and 1, and in event register ERC?, bits
0 and 1. The results can also be assigned to signal outputs
SIG123 at the analog interface with the help of the

SIG123 txt1.txt2.txt3

command.

Setting Command

Syntax:

UI_C_SET w1,w2,w3,w4

Value range w1, w2:



w1 < w2



Unom [V]

Value range w3, w4:



w3 < w4



Inom [A]

Default setting
or after RESET (*RST): 0,Unom,0,Inom

Query Command

Syntax:

UI_C_SET?

Sample response string:

UI_C_SET w1,w2,w3,w4

Parameters List

UL_H, UL_H? – Upper Limit Value for Voltage Setting

Function

UL_H defines the upper setting limit (soft-limit) for voltage setpoint
value Uset. The limit can be used to assure that output voltage is
not inadvertently set above a specified value.
The UL_H command corresponds to the ULIM command for the
SSP6XN Konstanter series as an upper limit value.
Thus

UL_H

can also be replaced with

ULIM

When the

ULIM?

query is executed,

UL_H +XXX.XXX

returned as a response. Values outside of the value range (Uset



Unom) are not accepted, and cause generation of an error

message and setting of an error bit in event register ERC.2. Unom
is the device-specific maximum nominal voltage. Entered numeric
values are rounded off to device-specific resolution.
