1 Power Sensor Remote Operation
The legal frequency suffix multipliers are any of the IEEE suffix multipliers, for example,
N O T E
KHZ, MHZ, and GHZ. If no units are specified the power sensor assumes the data is Hz.
PCT is the only legal unit for offset factors and can be omitted.
The frequency and offset data must be within range. Refer to the individual commands in
Chapter 4
Any offset values entered into the table should exclude the effect of the sensor.
Characterization of the test setup independently of the sensor allows the same table to be
used with any sensor.
Ensure that the frequency points you use cover the frequency range of the signals you want
to measure. If you measure a signal with a frequency outside the frequency range defined
in the frequency dependent offset table, then the power sensor uses the highest or lowest
frequency point in the table to calculate the offset.
To make subsequent editing of a frequency dependent offset table simpler, it is
recommended that you retain a copy of your data in a program.
Listing the Frequency Dependent Offset Table Names
To list the frequency dependent offset tables currently stored in the power
sensor, use the following command:
MEMory:CATalog:TABLe?
The power sensor returns the data in the form of two numeric parameters and
a string list representing all stored tables.
•
Each string parameter returned indicates the name, type and size of a stored
frequency dependent offset table:
•
For example, a sample of the response may look like:
560,8020,"Offset_1,TABL,220","Offset_2,TABL,340" ....
20
for their specified ranges.
<numeric_value>,<numeric_value>{,<string>}
The first numeric parameter indicates the amount of memory, in bytes,
used for storage of tables. The second parameter indicates the memory, in
bytes, available for tables.
<string>,<type>,<size>
The <string>, <type> and <size> are all character data. The <type> is
always TABL. The <size> is displayed in bytes.
