Network analyzer compatibility

Compatible with Keysight 8757D scalar network analyzer. Also useable with Keysight 8757A/C/E scalar network analyzers for making basic swept measurements

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

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 Keysight part number 8120-8806 master/slave interface cable.

5. 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.

Paths ΦM1 and ΦM2 are summed internally for composite modulation. Either path may be switched to any one of the modulation sources: Ext1, Ext2, internal1, internal2. The ΦM2 path is limited to a maximum rate of 1 MHz.

The ΦM2 path must be set to a deviation less than ΦM1. To avoid distortion and clipping, signals applied with any combination of ΦM1, ΦM2, or ΦM1+ ΦM2 should not exceed 1 Vpeak.

1. All AM specifications are typical. For carrier frequencies below 2 MHz or above 50 GHz, AM is useable but not specified. Unless otherwise stated, specifications apply with ALC on, deep AM off, and envelope peaks within ALC operating range (–20 dBm to maximum output power, excluding step-attenuator setting.)

2. Below 250 MHz with Option UNX or UNY low phase noise mode on, AM is useable but not recommended or specified.

3. Option 1SM scan modulation is available with Option 520 only, and provides exponential (log) AM with improved accuracy.In this mode, maximum output power is reduced up to 3 dB below 3.2 GHz.

4. ALC off is used for narrow pulse modulation and/or high AM depths with envelope peaks below ALC operating range (40 dB).Carrier power level will be accurate after a power search is executed.(See pulse modulation section for an explanation of power search).

5. Deep AM with ALC on provides increased AM depths and improved distortion, together with closed-loop internal leveling.This mode must be used with a repetitive AM waveform (frequency > 10 Hz) with peaks > –5 dBm (nominal, excluding step-attenuator setting).

6. Modulation depths greater than 40 dB require an external input greater than ± 1 V, and are not available with the internal modulation source.

7. If 600 Ω input impedance is selected, maximum input voltage is ± 6 V.

8. For Options 550 and 567, maximum rate is 80 kHz from 20 GHz to 40 GHz.

9. For Option 521, distortion specifications apply for envelope peaks within the range of -15 dBm to +24 dBm, excluding step-attenuator setting.

1. With ALC off, specs apply after the execution of power search. Specifications apply with Atten Hold Off (default mode for instruments with attenuator), or ALC level between –5 and +10 dBm or maximum specified power, whichever is lower. Above 50 GHz or below 50 MHz, pulse modulation is useable; however performance is not warranted. Pulse modulation does not operate if Option UNX or UNY low phase noise mode is on.

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 to 50 ms; the step attenuator (Option 1E1) 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. Power search may not operate above the maximum specified output power.
