WAVE
Queries the waveform data.
At 38400 bit/s, it would take approximately 40 seconds to retrieve 10000 points.
While the data is being retrieved, "DATA TRANSFR" is displayed (no measured values are displayed). In this situation, you cannot perform panel operations.
Because the data is being retrieved, integration continues.
Command
WAVE? <NRf>
Parameter
| Value | 1 to 16384 | The number of data points to query |
| -1 | Retrieves the next block of data |
Response (RS232C)
Returns the voltage and current values for the specified number of points of waveform data in the following format in response to WAVE? <NRf>. The hexadecimal numbers are 16-bit signed integers.
Voltage coefficient<NR3>_current coefficient<NR3>,voltage value (hexadecimal)_current value (hexadecimal),voltage value (hexadecimal)_current value (hexadecimal), . . .(the pattern is repeated for the specified number of points),END.
The interval between points is 10 µs.
Response (GPIB and USB)
Up to 256 characters can be returned as the response to a single query.
Returns the voltage and current values for the specified number of points of waveform data in the following format in response to WAVE? <NRf>. The hexadecimal numbers are 16-bit signed integers.
When the waveform data is 256 characters or less
Voltage coefficient<NR3>_current coefficient<NR3>,voltage value (hexadecimal)_current value (hexadecimal),voltage value (hexadecimal)_current value (hexadecimal), . . .(the pattern is repeated for the specified number of points),END.
When the waveform data is 257 characters or more
Voltage coefficient<NR3>_current coefficient<NR3>,voltage value (hexadecimal)_current value (hexadecimal),voltage value (hexadecimal)_current value (hexadecimal), . . .(the pattern is repeated until the total data length is 256 characters),CONT.
To query the next block of data, send the same query with parameter "-1." In response to "WAVE? -1," the KPM1000 returns the voltage and current values for the next block of the waveform data in the following format.
If there are more blocks of data to be retrieved:
Voltage value (hexadecimal)_current value (hexadecimal),voltage value (hexadecimal)_current value (hexadecimal), . . .(the pattern is repeated until the total data length is 256 characters),CONT.
If this is the last block of data to be retrieved:
Voltage value (hexadecimal)_current value (hexadecimal), . . . (the pattern is repeated for the remaining points),END.
The interval between points is 10 µs.
