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

Frequency settling time 28 ms typical

Amplitude settling time 10 ms typical

Number of points 2 to 1601

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 0 Hz (swept CW) to full range

Maximum Sweep Rate Maximum Max Span for

Start frequency sweep rate 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 100ms 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

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

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

for making basic swept measurements.

Digital sweep

Ramp (Analog) sweep

(Option 007)

4 During Ramp sweep operation, AM and Pulse Modulation are useable but not specified; FM and Phase

Modulation are not useable.

5 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.

6 For Master/Slave operation use Agilent Technologies part #8120-8806 Master/Slave interface cable.

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

8 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.
