Glossary
Corrected Data
There are two internal data arrays that hold \corrected data," one array for Channel 1,
and one for Channel 2. In addition to ratioing and averaging, corrected data has been
through time domain and calibration processing (if these features are ON at the time). Also ,
a user-denable \delay table" can aect corrected data, if used. Refer to the index of the
Operating and Programming manual under \delay table" to nd more information.
Delay T able
The HP 8530A has a delay table for each channel. When four parameter display is ON,
there is a delay table for each parameter in each channel (a total of eight). The delay
table allow users to grab , modify , and return measurement data to the instrument. Uses
are primarily in RCS applications , where users want to modify the time domain response
window . Refer to the index of the Operating and Programming manual under \delay table"
to nd more information.
DOS
Disc Operating System, the disc format used by IBM PCs and compatible computers .
F orm 1
An HP-IB data transfer format. F orm 1 is the native internal data format of the receiver .
It consists of a header byte , followed by three , 16 bit data words for each stimulus point.
F orm 1 oers very fast transfer speeds , and it can be converted to oating point data. (High
Speed F ast CW only oers F orm 1 output.)
F orm 2
An HP-IB data transfer format. F orm 2 is a 32 bit IEEE 728 format. This format is not
commonly used.
F orm 3
An HP-IB data transfer format. F orm 3 is the recommended format for use with HP 9000
Series 200/300 workstations . It consists of a header , a two-byte number indicating how
many bytes follow , then the real and imaginary data pairs for each stimulus point. F orm 3
follows the 64 bit IEEE 728 standard format.
F orm 4
An HP-IB data transfer format. F orm 4 is ASCII, originally used for PCs before F orm 5 was
created.
F orm 5
An HP-IB data transfer format. F orm 5 is the recommended format for use with IBM PCs
and compatibles . This is a 32 bit DOS-compatible oating point format.
F ormatted Data
There are two internal data arrays that hold \formatted data," one array for Channel 1, and
one for Channel 2. This data is scalar (magnitude-only) and reects display format, scaling,
and trace math processing.
Frequency List Mode
This mode is similar to Step Sweep mode , because it phase locks at each measurement
frequency . Frequencly List mode allows you to enter a list of frequencies you want to
measure . Y ou can select any number of frequencies (up to 801) and choose any frequencies
you want. Y ou can enter frequencies in any order , but the receiver will measure the
frequencies in sequential order from the lowest to the highest frequency .
