Anritsu S331D Store Sweep Trace Control Byte #16 10h, Recall Sweep Trace Control Byte #17 11h

Store Sweep Trace – Control Byte #16 (10h)

Description: Saves current trace to the next available memory location. Trace name can be set using control byte #9, “Set Reference Number” before executing this command.

Bytes to Follow: 0 bytes

Site Master Returns: 5 bytes

1-4) Time/Date Stamp (In long integer format)

5)Operation result:

255 (FFh) Operation Complete Byte

224 (E0h) Out of memory (Memory full)

238 (EEh) Time-out Error

Recall Sweep Trace – Control Byte #17 (11h)

NOTE: This command exists for backward compatibility with the S33xC models. Features new to the S33xD models are not available here. To access the new features, use Control Byte #33 (21h). This command cannot be used with a frequency converter module attached (Option 6 required).

Description: Queries the Site Master for sweep trace data.

Note: Before you can recall a sweep stored in non-volatile memory (trace numbers 1-200) you must build a trace table in the Site Master’s RAM. Use Control Byte #24 to build the trace table. Since the trace table exists in RAM, Control Byte #24 must be executed every time the Site Master’s power is cycled.

Bytes to Follow: 1 byte

0 = Last sweep trace before entering remote mode (sweep trace in RAM) 1- 200 = Specific saved sweep number (stored sweeps in Flash memory)

Site Master Returns:

1-2)	# of following bytes (total length - 2)
3-4)		Not Used
5-11)		Model Number (7 bytes in ASCII)
12-15)		Software Version (4 bytes ASCII)
16)	Measurement Mode3
17-20)		Time/Date (in Long Integer4)
21-30)		Date in String Format (mm/dd/yyyy)
31-38)		Time in String Format (hh:mm:ss)
39-54)		Reference number stamp (16 bytes in ASCII)
55-56)		# data points (130, 259, 517 or 400)

For all Site Master Modes:

57)Start Frequency5 (highest byte)

58)Start Frequency

59)Start Frequency

60)Start Frequency (lowest byte)

61)Stop Frequency (highest byte)
