E8257D H1K

Description

Description
The Keysight E8257D Option H1K provides extended low frequency coverage, with specified
leveled output power up to +7 dBm from 100 kHz to 250 kHz. The Keysight E8257D Option 1EA
or 1EU (high output power) is required with Option H1K.
In all other respects, the E8257D Option H1K is the same as the standard E8257D.

Performance Verification

These specifications apply over a 15 to 35 °C temperature range. Note that Keysight level
accuracy specifications include flatness uncertainty, attenuator setting uncertainty and
measurement uncertainty (which becomes significant at lower power levels.

a. 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 >
-10 dBm, is typically < 0.3 dB. In ramp sweep mode (with Option 007), specifications are typical.
Specifications do not apply above the maximum specified power.
Power level accuracy is verified over the full frequency range and power range of the instrument.
This procedure measures only the frequency range extended by this option.
The higher power range (> -45 dBm) is measured using a power meter with a calibrated power
sensor. The lower range (≤ -50 dBm) is measured with a spectrum analyzer. For power levels
≤ -50 dBm, the spectrum analyzer's internal preamplifier is used to boost the lower power levels.
