Trace Data All

This command transfers VNA trace data from the instrument to the controller for all traces that are currently displayed. The trace data returns with no delimiter between each trace using the same IEEE definite length arbitrary block response of the Trace Data command.

After the usual header of arbitrary block, there is additional header information to support parsing the remaining data. This header has components in the following order: (1) A two-byte integer to return the number of display points per trace. All traces share the same display point value. (2) A two-byte integer to show the last update point of the traces. All traces share the same value of the 'last update point.' (3) A two-byte integer contains the trace flag value. The bits in the trace flag maps to a trace number to indicate whether the trace data includes that trace. Each trace uses 2 bits to represent what types of trace data are included. The first bit (if set) means live trace is included. The next bit(if set) means memory trace is included. For example, a trace flag of value 0x15 (0b010101) represents data of the live trace 1, 2, and 3 are included. Another example, a value of 0x17 (0b010111), which means live trace 1 to trace 3 are included. Plus, the memory trace 1 is also included. (4) a two-byte format flag. The format value is a bit-mask uses to indicate the format of trace data. The supported formats are real numbers or complex numbers. For instance, if the format flags have the value, Ox7 (0b1111) means trace 1 to trace 4 contains complex numbers; if the value is 0x2 (0b0010), then only trace 2 contains complex numbers. All other trace data is in real numbers (5) eight-byte trace data - This is the sector that contains trace data. If trace data in real numbers format, then each data point will be a double-precision value. If the trace data is a complex number, then each data point will consits of a 2X of an eight-byte value with the first eight-byte is the real part of a complex number, and the second eight-byte is the imaginary part of a complex number. The traces data return in increasing order. The memory trace data follows each live trace (if memory trace included) otherwise the next live trace of the next trace follows.

Get Operation Status

This command requests information about the current status of the instrument. Each bit of the return value represents some operation. Only a subset of the bits are implemented for each application. The number returned is the decimal representation of the bit-wise OR of the enabled bits:

Trace Data

Return raw trace data in real and imaginary pair. Data is transferred from the instrument as an IEEE definite length arbitrary block response, which has the form <header><block>. The format of the block data depends on the current data format setting (FORMat[:READings][:DATA]).

This command takes a single integer parameter specifying the trace number to transfer. If the parameter value is out of the range of valid trace numbers, the first trace (1) will be transferred. (Currently only one trace is supported, so this parameter has no effect.)

The ASCII header specifies the number of data bytes. It looks like #AX, where A is the number of digits in X and X is the number of bytes in the <block>.

The first character is the literal ascii hash '#' 043. The second character (A) is a single ascii digit '1' to '9' describing the number of bytes in the length section (X). This number is called nlength. The next nlength bytes make up an ascii string of digits '1' to '9' describing the length of the <block> data.

For example, if the first 6 bytes are #49999, then the nlength is 4. The 4 bytes of length are 9999. After that follows the <block>, which would be 9999 bytes in size. The query command will return a #0 if data is invalid for the active trace.

Restart Continuous Sweep

Restart the sweep/measurement in continuous mode. If :SENSe{[1]|2|3|4}:SWEep:MODE is set to SINGle, this command is ignored and results an error -230.

Initiate Single Sweep

Initiates a sweep/measurement. If :SENSe{[1]|2|3|4}:SWEep:MODE is set to CONTinuous, or if :SENSe{[1]|2|3|4}:SWEep:MODE is set to SINGle but the current sweep has not completed yet, this command is ignored. Use this command in combination with :STATus:OPERation? or *OPC? to synchronize the capture of one complete set of data. When this command is sent, the "sweep complete" bit of :STATus:OPERation? is set to 0, indicating that the measurement has not completed. The data collection is then triggered. The controlling program can poll :STATus:OPERation? to determine the status. When the "sweep complete" bit is set to 1, data is ready to be retrieved.

This command is also overlapped, so alternatively, *OPC? can be used to wait for completion of the measurement without polling. When this command is received, the pending operation bit is set. The pending operation will finish once the sweep/measurement is done. Clients can use *OPC? to 'block' until the sweep/measurement is completed.
