  • BANDWIDTH 101 Set Sweep time Background Sweep time defines the display update rate. Note that sweep time and RBW/VBW are in trade-off. Faster sweep time updates display more frequently but makes RBW and VBW wider, reducing the capability to separate signals at close frequencies. Panel operation 1. Press the BW key. BW 2. Press F3 (Swp tm) To switch between Auto and Manual setting. Swp TmAuto ManF 3 In the Manual mode, the manual sweep time icon appears. 3. When Manual mode is selected, enter the sweep time using the Numerical/Unit keys. BK SPdBEnterGHz /SecmSecMHz /kHz / Secμ Mode Auto Sweep time is automatically set. Manual Sweep time is manually set. Range 50ms to 25.6s, 1us resolution Note When in the Auto mode, GSP830 is optimized for fast sweep time. For narrower RBW settings, like 300 Hz or 3 KHz, this optimization will cause slightly higher phase noise. To reduce the phase noise level, slow down the sweep time using manual setting. Average Waveform Background The GSP-830 averages the waveform for a user-defined or system-defined number before it is displayed. This feature smoothes the noise level to a great extent, but slows down the display update rate. Panel operation (Method1) 1. Press the BW key. BW
