Two-tone (master/slave) measurements

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

Also useable with Agilent 8757A/C/E and Gigatronics 8003 scalar network analyzers for making basic swept measurements.

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.

Step attenuator6 0 to 115 dB in 5 dB steps Maximum available power in CW mode (measured)

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.

Attenuator hold range Minimum From –15 dBm to maximum specified

output power with step attenuator in 0 dB position. Can be offset using step attenuator.

Level accuracy (measured)

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 apply to 18 GHz only. From 18 to 20 GHz, typical level accuracy degrades by 0.2 dB. 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 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.
