GPIB Operation ML24xxA Native Commands
ML2437A/38A OM/PM PN: 10585-00001 Rev. P 8-53
MMRST (Min Max Tracking reset)
MNGDB (Output Min Graph Binary Data)
MNGD (Output Min Graph Data)
Syntax: MMRST <c>
c: 1 or 2
Remarks: This command resets the min/max values when in 'Readout' or 'Power
vs. Time' mode. In profile mode, this command is used to reset the
channels min/max values.
Syntax: MNGDB
Remarks: Available in graph modes only. Outputs in binary form the min graph
data to the GPIB in the long integer form of 1024 bits per dB as a
definite length arbitrary block response data. The C programming
example 'Binary output decoding' shows how to extract the binary data.
The response form is as follows:
MNGDB <#><length><number_of_bytes><data_byte_1><data_byte_2>
...
<data_byte_n><\n>
<length> number of ASCII characters make up the number_of_bytes
value
<number_of_bytes> number of bytes of data contained in rest of the
string
<data_byte_n> four of these values makes up the long integer.
For example: FF FF D1 64 = –11932 As it is based on 1024 per dB,
divide by 1024 to get the dB value (–11.652).
Syntax: MNGD
Remarks: Available in graph modes only. Outputs in ASCII form the min graph
data. The format is as follows:
MNGD
<number_of_elements>,<element_1>,<element_2>,<element_n>...<\n>
The first number in the string is the number of elements to follow, and is
always 200 for the ML243xA.
