Atec Agilent-8703A - Manual (Page 5)

Specifications describe the instrument’s warranted performance for the
temperature range of 23 ±3°C after a three hour warm-up. Supplemental
characteristics describe useful, non-warranted performance parameters.
These are denoted as “typical” or “nominal”.

5 For optical-to-optical devices, (dBo) = 10 log (#2 optical power
(W p-p) / #1 optical power (W p-p))
6 For optical-to-electrical devices, slope responsivity (dBe) = 20 log
(( ∆ current (A p-p) / ∆ optical power (W p-p)) / 1 A/W)
7 For electrical-to-optical devices, slope responsivity (dBe) = 20 log
(( ∆ optical power (W p-p) / ∆ current (A p-p)) / 1 W/A)
8 Measurement range can be shifted upward by externally adding
attenuation in the signal path during calibration and measurement.
3 Limited by maximum lightwave source output power, maximum
lightwave receiver input power, maximum microwave output power
and system noise floor. Specified for an IF bandwidth of 10 Hz and an
averaging factor of 16 after an appropriate calibration has been
performed (i.e. response & isolation calibration for optical tests,
response & match and isolation calibration for electrical-to-optical
and optical-to-electrical tests).
4 8703A Option 100 systems will typically see 1 dBo less dynamic range
than is shown for optical transfer function and reflection measurements.
Optical-to-electrical transfer function measurements will typically
see 2 dBe less.
