N1913A/14A EPM Series Power Meters Performance Characteristics
Specifications describe the instrument’s warranted performance and apply after a
30 minute warm-up. These specifications are valid over its operating/environmental
range unless otherwise stated and after performing a zero and calibration procedure.
Supplemental characteristics (shown in italics) are intended to provide additional
information, useful in applying the instrument by giving typical (expected), but not
warranted performance parameters. These characteristics are shown in italics or labeled
as “typical,” “nominal” or “approximate.”

Display units
Absolute: Watts or dBm
Relative: Percent or dB
Display resolution
Selectable resolution of: 1.0, 0.1, 0.01 and 0.001 dB in logarithmic mode, or 1, 2, 3 and 4 significant digits in linear mode
Default resolution
0.01 dB in logarithmic mode or three digits in linear mode
Accuracy
Absolute accuracy
± 0.02 dB (Logarithmic) or ± 0.5% (Linear). Please add the corresponding power sensor linearity percentage from
Tables 6, 9 and 10 (for the E-Series sensors), Table 14 (for the 8480 series sensors) and Table 16 (for N8480 sensors) to
assess the overall system accuracy.
Relative accuracy
± 0.04 dB (Logarithmic) or ± 1.0% (Linear). Please add the corresponding power sensor linearity percentage from the
mentioned tables above to assess the overall system accuracy.
Zero set
(digital settability of zero)
0.0000175% (meter only)
Power sensor dependent (refer Table 1), this specification applies when zeroing is performed with sensor input
disconnected from the POWER REF.
Zero drift of sensors
This parameter is also called long term stability and is the change in the power meter indication over a long time
(within one hour) at a constant temperature after a 24-hour warm-up of the power meter. Sensor dependent, refer to
Table 1. For E9300 sensors, refer to Table 11 for complete data.
Measurement noise
Sensor dependent, refer to Tables 1 and 2. For E9300 sensors, refer to Table 11 for complete data
Effects of averaging on noise
Averaging over 1 to 1024 readings is available for reducing noise. Table 1 provides the measurement noise for a
particular power sensor with the number of averages set to 16 for normal mode and 32 for x2 mode. Use the
“Noise Multiplier” for the appropriate mode (normal or x2) and number of averages to determine the total measurement
noise value.
For example: For a Keysight 8481D power sensor in normal mode with the number of averages set to 4, the measurement
noise is equal to: (< 45 pW x 2.75) = < 124 pW
