Ramp (analog) sweep

(Option 007)

1

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.

ALC on or off (without power search) < 3 ms (typ)

1. Maximum power specification is warranted from 15 to 35 ºC, and is typical from 0 to 15 ºC. Maximum power over the
35 to 55 ºC range typically degrades less than 2 dB unlessotherwise stated.

2. With I/Q modulation on, maximum power specification is typical. With external inputs enabled, √(I2+ Q2) > 0.2 V

.

3. With harmonic filters switched off. With filters on, maximum output power is reduced 3 dB for frequencies below 2 GHz.

4. With I/Q modulation on, maximum power specification is typically reduced 3 dB.

5. Maximum power over the 35 to 55 ºC range typically degrades less than 4 dB. With I/Q modulation on, maximum power
specification is typically reduced 5 dB.

6. The step attenuator provides coarse power attenuation to achieve low power levels. Fine power level adjustment is
provided by the ALC (Automatic Level Control) within the attenuator hold range.

7. To within 0.1 dB of final amplitude within one attenuator range. Add 10 to 50 ms when using power search.

1. Specifications apply in CW and list/step sweep modes over the 15 to 35 ºC temperature range, with attenuator hold off

(normal operating mode). Degradation outside this range, for ALC power levels > –5 dBm, is typically < 0.3 dB. In ramp sweep
mode (with Option 007), specifications are typical. For instruments with Type-N connectors (Option 1ED), specifications are
degraded typically 0.2 dB above 18 GHz. Specifications do not apply above the maximum specified power.

2. If external inputs are used, specification applies with input level √(I2+ Q2) = 0.3 V

rms

and I/Q modulator attenuation is

internally optimized based on input levels.

3. Measured with symbol rate > 10 kHz and power ≤ 0 dBm.

4. Relative to ALC on, after power search is executed. When applying external I/Q signals with ALC off, output level will vary

directly with I/Q input level.

5. Options 532 and 544: 0.02 dB/°C (typ) above 2 GHz.

6. Compatible with Agilent EPM Series (E4418B and E4419B) power meters.

Paths FM1 and FM2 are summed internally for composite

modulation. Either path may be switched to any
one of the modulation sources: Ext1, Ext2, internal1,
internal2. The FM2 path is limited to a maximum
rate of 1 MHz. The FM2 path must be set to a
deviation less than FM1.

1. Calculated from phase noise performance in CW mode only at +10 dBm. For other frequencies, data rate, or bandwidths,
please contact your sales representative.

2. Through any combination of path1, path2, or path1 + path2.

3. Specifications apply in CW and list/step sweep modes. During ramp sweep operation (Option 007), 3 dB bandwidth is typically
50 kHz to 10 MHz (FM1 path), and 50 kHz to 1 MHz (FM2 path).

4. AM specifications are typical. For carrier frequencies below 2 MHz, AM is useable but not specified. Unless otherwise stated,
specifications apply with ALC on and envelope peaks within ALC operating range (–15 dBm to maximum specified power,

5. ALC Off is used for narrow pulse modulation and/or high AM depths, with envelope peaks below ALC operating range.
Carrier power level will be accurate after a Power Search is executed.

6. ALC On with Deep AM provides high AM depths together with closed-loop internal leveling. This mode can be used with a

1. With ALC off, specifications apply after the execution of power search. Specifications apply with Atten Hold Off (default
mode), or ALC level between –5 and +10 dBm or maximum specified power, whichever is lower .

2. Power search is a calibration routine that improves level accuracy with ALC off. The instrument microprocessor momentarily
closes the ALC loop to find the modulator drive setting necessary to make the quiescent RF level equal to an entered value,
then opens the ALC loop while maintaining that modulator drive setting. When executing power search, RF power will be present
for typically 10-50 ms; the step attenuator can be set to automatically switch to maximum attenuation to protect sensitive
devices. Power search can be configured to operate either automatically or manually at the carrier frequency, or over a
user-definable frequency range.

3. With attenuator in 0 dB position. Video feed-through decreases with attenuator setting.

timing signal generated by marker 1.

Event 2 output In real-time mode, outputs a data enable signal for gating

external equipment, for use with internal baseband generator
