Using Frequency Dependent Offset Tables

1-44 HP E4418B/E4419B Programming Guide

Each string parameter returned indicates the name, type and size of a

stored frequency dependent offset table:

• <string>,<type>,<size>

The <string>, <type> and <size> are all character data. The

<type> is always TABL. The <size> is displayed in bytes.

For example, a sample of the response may look like:

560,8020,“Offset_1,TABL,220”,”Offset_2,TABL,340” ....

Naming Frequency Dependent Offset Tables

To rename a frequency dependent offset table use:

MEMory:TABLe:MOVE <string>,<string>

The ﬁrst <string> parameter identiﬁes the existing table name, and the

second identiﬁes the new table name.

The following rules apply to frequency dependent offset table names:

a) Table names use a maximum of 12 characters.

b) All characters must be upper or lower case alphabetic characters,

or numeric (0-9), or an underscore (_).

c) No spaces are allowed in the name.

Reviewing Table Data

To review the data stored in a frequency dependent offset table, use the

following commands:

• MEMory:TABLe:SELect "Offset1"

Select the sensor calibration table named “Offset1”.

• MEMory:TABLe:SELect?

Query command which returns the name of the currently selected

table.

• MEMory:TABLe:FREQuency:POINTs?

Query command which returns the number of stored frequency

points.

• MEMory:TABLe:FREQuency?

Query command which returns the frequencies stored in the

frequency dependent offset table (in Hz).
