4. Setting commands for calibrator's functions

4.1. Setting harmonics

Function

Prepare calibrator to receive block of data

Command

BD_<VAL_INT>[CR][LF]

Description

Prepare calibrator to receive <VAL_INT> bytes of data.
Command is used to transmit data (table) of harmonic shape (4096 samples) to a calibrator.

Parameter(s)

<VAL_INT> = 16384



Prepare calibrator to receive harmonic table

Example(s)

BD_16384[CR][LF]

Example answer

OK[CR][LF]

Function

Write data to calibrator

Command

WR_<DATA><CRC>[CR][LF]

Description

Write data (table of samples) of harmonic shape to the calibrator. The table of shape consists
of 4096 samples (one period).
Each sample of shape is coded as a 4 ASCII chars (hexadecimal value of Sample).
Sample = ShapeSample • 4095 + 4096; where:

Sample



calculated sample in range from 1…4096…8191 (natural number)

ShapeSample



sample of a shape (shape normalized to



1 values)

ShapeSample = 0



1000 hex value (4096)

ShapeSample = -1



0001 hex value (1)

ShapeSample = +1



1FFF hex value (8191)

Parameter(s)

<DATA>



binary data coded as an ASCII chars. Max. size of <DATA> is 114 chars (29

samples)
<CRC>



4 bytes of CRC checksum

Example(s)

WR_10000FFA0FF40FEE0FE70FE10FDB0FD50FCE0FC80FC20FBB0FB50FAF0FA90FA
20F9C0F960F8F0F890F830F7D0F760F700F6A0F630F5D0F570F51F387[CR][LF]

(116 bytes of first 29 samples of sine-

shape, last 4 bytes are CRC “F387” counted from

<DATA>)

Example answer

OK[CR][LF]

Function

Harmonics

– uploading to channels

Command

H2CH_<CHANNEL>[CR][LF]

Description

Rewrite shape wi

th harmonics from the C300’s receiving buffer to the memory.

Parameter(s)

<CHANNEL> = 0



change default SIN shape to the new one

<CHANNEL> = 1



set harmonics shape to the U1

<CHANNEL> = 2



set harmonics shape to the U2

<CHANNEL> = 3



set harmonics shape to the U3

<CHANNEL> = 4



set harmonics shape to the I1

<CHANNEL> = 5



set harmonics shape to the I2

<CHANNEL> = 6



set harmonics shape to the I3

Example(s)

H2CH_1[CR][LF]

(set harmonics shape to the U1 channel)

Example answer

OK[CR][LF]

START

Prepare calibrator

to data transfer

BD_16384

Send data to

calibrator

WR_

Upload buffer to

channel memory

H2CH_

Send

FREQDIV_1

Switch harmonic ON in uploaded

channel

YES

Send data

to next

channel?
