1. Operational, but unspecified, down to 100 kHz.

3. Time from GPIB trigger to frequency within 0.1 ppm of final frequency above 250 MHz or within 100 Hz below 250 MHz.

4. Add 12 ms (typical) when switching from greater than 3.2 GHz to less than 3. 2 GHz.

5. N is a factor used to help define certain specifications within the document.

6. To optimize phase noise use 5 dBm ± 2 dB.

7. Standard performance applies to units with serial numbers ending with 48050000 or greater. For units with lower serial numbers, refer to the data sheet shipped with the unit or the version of this document dated November 5, 2007.

Two-tone (master/slave) Two PSG’s can synchronously track each other, with measurements5 independent control of start/stop frequencies Network analyzer Fully compatible with Agilent 8757D scalar compatibility network analyzer6

Also useable with Agilent 8757A/C/E scalar network analyzers for making basic swept measurements.

1. 19 ms (typ) when stepping from greater than 3.2 GHz to less than 3.2 GHz.

2. During ramp sweep operation, AM, FM, phase modulation, and pulse modulation are useable but performance is not guaranteed.

3. Minimum set table sweep span is proportional to carrier frequency and sweep time. Actual sweep span may be slightly different than desired setting for spans less than [0.00004% of carrier frequency or 140 Hz] x [sweep time in seconds]. Actual span will always be displayed correctly.

4. Typical accuracy for sweep times > 100 ms can be calculated from the equation: [(0.005% of span)/(sweep time in seconds)] ± timebase. Accuracy is not specified for sweep times < 100 ms.

5. For master/slave operation use Agilent part #8120-8806 master/slave interface cable.

6. When measuring low-pass devices in AC mode, dynamic range may be reduced up to 10 dB below 3.2 GHz. A n external highpass filter may be required to remove 27 kHz pulse source feed-through (For instruments operating from 10 MHz to 20 GHz with 3.5 mm connectors, use Bias Tee part number 5086-7322. For instruments operating from 10 MHz to 50 GHz with 2.4 mm connectors, use Bias Tee part number 5086 -7484.)

7. GPIB system interface is not supported with 8757A/C/E, only with 8757D. As a result, some features of 8757A/C/E, such as frequency display, pass-through mode, and alternate sweep, do not function with PSG signal generators.
