Ramp (analog) sweep
(Option 007)
1
Operating modes Step sweep of frequency or amplitude or both (start to stop)
List sweep of frequency or amplitude or both (arbitrary list)
Sweep range
Frequency sweep
Within instrument frequency range
Amplitude sweep Within attenuator hold range
Dwell time 1 ms to 60 s
Number of points 2 to 1601 (step sweep)
2 to 1601 per table (list sweep)
Triggering Auto, external, single, or GPIB
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
100ms 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 36.8 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

Sweep time (forward sweep, not including bandswitch and retrace intervals)
Resolution 1 ms
Manual mode Settable 10 ms to 99 seconds
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 PSG’s 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 scalar network analyzers
for making basic swept measurements.

1. During Ramp sweep operation, AM and Pulse Modulation are useable but not specified; FM, Phase
Modulation, 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 < 10 ms.
4. For Master/Slave operation use Agilent Technologies part #8120-8806 Master/Slave interface cable.
5. When measuring low-pass devices in AC mode, dynamic range may be reduced up to 10dB below 3.2 GHz
6. 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.
