Anritsu S332D Select DTF Windowing Control Byte #31 1Fh, Recall Sweep Trace Control Byte #33 21h

Select DTF Windowing – Control Byte #31 (1Fh)

Description: Select DTF Windowing Methods.

DTF windowing allows you to make a trade off between side lobe height and resolution.

Bytes to Follow: 1 byte

1)Windowing Method

00h = Rectangular (finest resolution, highest side lobes)

01h = Nominal Side Lobe (balance between resolution and side lobes) 02h = Low Side Lobe

03h = Minimum Side Lobe

Site Master Returns: 1 byte

1)255 (FFh) Operation Complete Byte

224 (E0h) Parameter Error: Invalid DTF Windowing Method

238 (EEh) Time-out Error

Bytes to Follow: 2 bytes

1)Trace Math Operation 00h = Off

01h = Addition

02h = Subtraction

2)Trace on which to Perform Math Operation (1 to 200)

Site Master Returns: 1 byte

1)255 (FFh) Operation Complete Byte

224 (E0h) Parameter Error: Invalid Trace Math Operation

238 (EEh) Time-out Error

Recall Sweep Trace – Control Byte #33 (21h)

NOTE: This command is new to the S33xD. Use it instead of Control Byte #17 to access new features.

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 cy- cled.

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)
