Maximum lnput (without damage) Levels Total Power:

+20 dBm (O.lW, 2.2 Vrms) with 0 dB input attenuation

+30 dBm (lW, 7.1 Vrms) with 2 10 dB input attenuation

DC: +-7.1V

AC (<I00 Hz): 7.1 VrmsPeak Pulse Power:

+50 dBm (100W, <10 psec pulse width, 0.01 To duty cycle) with input attenuation 2 3 0 dB

Gain Compression

<0.5 dB for a - 10 dBm input level with 0 dB input attenuation.

Average N o i ~Level

The displayed average noise level determines sensitivity (minimum discernible signal). Signals at this input level peak approximately 3 dB above the displayed noise.

AMPLITUDEACCURACY

With AUTO sweep time selected, amplitude accuracy is determined by one or more of the following factors, depending on the measurement technique.'

Calibrator Output

-10 dBm +- 0.3 dB (into S(X2)

35 MHz +- 400 kHz

ReferenceLevel

10-dB steps and a 12-dB vernier for calibrated Reference Level adjustment from - 112 dBm to

+60 dBm.'

Vernier Accuracy: +. 0.5 dB

Frequency Response

Frequency response, measured with 0 or 10 dB input attenuation, includes input attenuator flat- ness, mixer flatness, and band-to-band amplitude variation:

lnput Attenuator

0 dB to 70 dB of input attenuation selectable in 10- dB steps

Step Accuracy:

0 dB to 60 dB, 0.01 to 18.0 GHz: <k 1.0 dB per 10-dB step

Maximum Cumulative Step Error:

0 dB to 60 dB, 0.01 to 18.0 GHz: < k 2.4 dB

Bandwidth Switching(Amplitude Variation)

Bandwidths 3 MHz to 300 kHz: < k 0.5 dB

Bandwidths 3 MHz to 1 kHz: < + 1.O dB

2When switching to or from the Alternate IF, the REF LEVEL CAL and the FREQ CAL should be readjusted. Without readjustment, an additional reference level

error of

+1 dB and an additional

frequency readout

error of

+- 1 MHz may result.
