Operating modes

• Synthesized frequency sweep

(start/stop), (center/span), (swept CW)

• Power (amplitude) sweep (start/stop)

• Manual sweep

RPG control between start and stop frequencies

• Alternate sweep

Alternates successive sweeps between current and

stored states

Z-axis intensity or RF amplitude pulse

Functions

M1 to center, M1/M2 to start/stop, marker delta

Two-tone (master/slave)

Two PSGs can synchronously track each other, with

independent control of start/stop frequencies

Network analyzer compatibility

Fully compatible with Agilent 8757D scalar

Also useable with Agilent 8757A/C/E scalar network

Ramp (analog) sweep

(Option 007)

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

specified; wideband AM and I/Q modulation are not useable.

2. Minimum settable 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.

3. 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.

4. For master/slave operation, use Agilent part number 8120-8806 master/slave interface cable.

5. When measuring low-pass devices in AC mode, dynamic range may be reduced up to 10 dB below 3.2 GHz. An external

highpass filter may be required to remove 27 kHz pulse source feed-through (11742A 45 MHz to 26.5 GHz blocking capacitor

recommended).

6. GPIB system interface is not supported with 8757A/C/E, only with 8757D. As a result, some features of the 8757A/C/E, such as

frequency display, pass-through mode, and alternate sweep, do not function with PSG signal generators.
