Time Scale Factor (MB-OFDM)
1 (See MB-OFDM Standard Setups/Presets Table.)
1/16 (.0625) - 16
scales the timebase of the signal used for measurement and analysis in a design or debug environment where the symbol rate and DAC Digital to Analog Converter: A device that takes a digital representation of a signal and transforms it into a facsimile of its original form. (Digital to Analog Converter) clocking is scaled at a faster or slower rate. For example, a test signal can be scaled with a symbol rate of 3.2 kHz kiloHertz: A radio frequency measurement (one kilohertz = one thousand cycles per second). instead of 3.2 MHz Megahertz: A unit of frequency equal to one million hertz or cycles per second. by entering: Time Scale Factor = 0.001, which results in a correct analysis.
The checkbox decides whether changes to the also change the , Search Length and Packet Avg RBW. When this checkbox is selected, the time/frequency parameters mentioned above "track" changes in the . The default for this checkbox is selected.
When the checkbox is selected, the demodulation uses the Factor entry to scale the hopping frequency offset of the signal. When cleared, the hopping frequency offset will remain fixed at 528 MHz (regardless of Factor entry).
The default for the checkbox is cleared (fixed hopping frequency offset of 528 MHz). This is different from previous versions (7.00 and earlier) of the 89600 VSA software where the determined the hopping frequency offset.
If the entry is greater than 1 and the checkbox is cleared, the bands will overlap.
