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
Sweep span range Settable from minimum 2 to full range
Maximum sweep rate Start frequency Maximum sweep rate Max span for
100 ms sweep
250 kHz to < 0.5 GHz 25 MHz/ms 2.5 GHz
0.5 to < 1 GHz 50 MHz/ms 5 GHz
1 to < 2 GHz 100 MHz/ms 10 GHz
2 to < 3.2 GHz 200 MHz/ms 20 GHz
≥ 3.2 GHz 400 MHz/ms 40 GHz
Frequency accuracy ± 0.05% of span ± timebase (at 100 ms sweep time, for
sweep spans less than maximum values given above)
Accuracy improves proportionally as sweep time increases 3
Sweep time (forward sweep, not including bandswitch and retrace intervals)
Manual mode Settable 10 ms to 200 seconds
Resolution 1 ms
Auto mode Set to minimum value determined by maximum sweep
rate and 8757D setting
Triggering Auto, external, single, or GPIB
Markers 10 independent continuously variable frequency markers
Display Z-axis intensity or RF amplitude pulse
Functions M1 to center, M1/M2 to start/stop, marker delta
Two-tone (master/slave)
measurements
4 Two PSGs can synchronously track each other, with
independent control of start/stop frequencies
Network analyzer compatibility Fully compatible with Agilent 8757D scalar
network analyzer 5
Also useable with Agilent 8757A/C/E and Gigatronics
8003 scalar network analyzers for making basic swept
measurements. 6
Ramp (analog) sweep

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.
