Sweep Type = Swept
Detector = Normal, Peak,
Sample or Negative Peak
Detector = Average
Sweep Type = FFT

Bandwidth (10 dB)
Frequency Limitations
External Triggers
a. The highest allowed mixer level depends on the attenuation and IF Gain. It is nominally 10 dBm +
input attenuation for Preamp Off and IF Gain = Low.
b. Noise will limit trigger level range at high frequencies, such as above 13 GHz.
Specifications
170 dBm

Level
Useful range limited by noise
Highest allowed mixer level
Triggers on the signal before detection, which is
similar to the displayed signal
Triggers on the signal before detection, but with a
single-pole filter added to give similar smoothing
to that of the average detector
Triggers on the signal envelop in a bandwidth
wider than the FFT width
50 to 10 dBm plus attenuation (nominal)
2 dB + Absolute Amplitude Accuracy (nominal)
18 MHz (nominal)
If the start or center frequency is too close to zero,
LO feedthrough can degrade or prevent triggering.
How close is too close depends on the bandwidth.
