6-24 MTS-1700 SERIES OPERATION AND REFERENCE MANUAL
MANTA TEST SYSTEMS
CU A002 15A
•
The anti-alias filter is automatically set to one half of the playback rate by this
command.
•
Valid values are 2.00 - 30.00 (kHz)
FPD#,#,#,#
Fault Playback Data
•
This command specifies one set of data points for fault playback.
•
The arguments specify the value of Va, Vb, Vc and I respectively (In I1-LOW
and I3 current modes).
•
Valid values are 0 - 16,383 (binary offset code)
•
Each successive FPD command stores the next set of data points into the MTS-
1710’s fault playback data buffer. This data buffer is reset when an FPM#
command, or LOC command, is sent.
•
See Section 7.3.1 for details
•
When the MTS-1720 is connected, and the I3-WYE current mode is selected,
the FPD command takes six arguments, and is of the form FPD#,#,#,#,#,#
NOTE:
See Section 7 for complete details on use of fault playback commands.

Programmable Waveform Control
•
Valid values are 0 - 3
0 - programmable waveform off
1 - programmable waveform on
2 - reset programmable waveform data table and selects the 720 point (every 1/2
degree) 8-bit data definition mode
3 - reset programmable waveform data table and selects the 1440 point (every
1/4 degree) 14-bit data definition mode
PWD# Programmable
Waveform
Data
•
This command is used to define the individual waveform data points for each
half degree (or each quarter degree if 14 bit mode is selected) in the waveform
•
Valid values are 1 - 255 (binary offset code) when 8 bit data definition mode is
selected
1 = -
x VmaxRMS for voltages or -
x ImaxRMS for current
2 = - (126/127 x
VmaxRMS) for voltages or - (126/127 x
ImaxRMS) for
current
.
.
128 = 0 output
129 = (1/127 x
VmaxRMS) for voltages or (1/127 x
ImaxRMS) for
current
.
.
255 =
Vmax for voltages or
x Imax for current
