1. For DELAY–1: ARANGE
OFF
For DELAY 0; NPLC .1 ,
unspecified reading rates of
greater than 500/Sec are
possible.
2. Additional error beyond±1°
C. but within ±5°C of last
ACAL.
For ACBAND > 2 MHz,
use 10 mV range
temperature coefficient for
all ranges.
3. Specifications apply from
full scale to 5% of full
scale. DC
< 10% of AC, sine wave
input, crest factor=1.4, and
PRESET. Within 24 hours
and ±1°C of last ACAL. LO
to Guard switch on.
Add 2 ppm of reading
additional error for Agilent
factory traceability of 10V
DC to US NIST.
Maximum DC is limited to
400V in ACV function.
Common Mode Rejection
For 1 kW imbalance in LO lead, > 90 dB, DC – 60 Hz.
