Differential data encoding can be described by the following equation: transmittedbit i()= databit i( –1).databit i() For a bit-by-bit illustration of the encoding process, see the following illustration: 0 101 00 1 100 101 raw (unencoded) data change = no change = 1111010101111 differentially encoded data 162 Chapter 7 Custom Real Time I/Q Baseband Working with Differential Data Encoding How Differential Encoding Works Differential encoding employs offsets in the symbol table to encode user-def

Chapter 2 Basic Operation Configuring the RF Output Configuring a Ramp Sweep for a Master/Slave Setup This procedure shows you how to configure two PSGs and an 8757D to work in a master/slave setup. 1. Set up the equipment as shown in Figure 2-7. Use a 9-pin, D-subminiature, male RS-232 cable with the pin configuration shown in Figure 2-8 on page 46 to connect the auxiliary interfaces of the two PSGs. You can also order the cable (part number 8120-8806) from Agilent Technologies. By connecting t

The RF output changes to the frequency value of the table row containing the cursor and 1.000 000 000 00 is displayed in the AMPLITUDE area of the display. 2. Observe and record the measured value from the power meter. 3. Subtract the measured value from 0 dBm. 4. Move the table cursor over the correction value in row 1. 5. Press Edit Item > enter the difference value from step 3 > dB. The signal generator adjusts the RF output amplitude based on the correction value entered. 6. Repeat ste

Use a Root Nyquist filter when you want to place half of the filtering in the transmitter and the other half in the receiver. The ideal root-raised cosine filter frequency response has unity gain at low frequencies, the square root of raised cosine function in the middle, and total attenuation at high frequencies. The width of the middle frequencies is defined by the roll off factor or Filter Alpha (0 < Filter Alpha < 1). • Nyquist is a raised cosine pre-modulation FIR filter. You can use a Nyqu

The EXT indicator is activated in the AMPLITUDE area of the display. NOTE For signal generators with Option 1E1, notice that the ATTN HOLD (attenuator hold) annunciator is displayed. During external leveling, the signal generator automatically uncouples the attenuator from the ALC system for all external leveling points. While in this mode, the RF output amplitude adjustment is limited to -20 to +25 dBm, the adjustment range of the ALC circuitry. For more information, see “External Leveling wit
