61. Accuracy with sample rate 1M per second and aperture 1µs.
62. Verified with sine wave input and DC content ≤3% of range.
63. For AC coupling, maximum crest factor of 5.
64. For DC coupled, 0dB reference frequency is 3Hz. For AC coupled, 0dB reference frequency is
1kHz. For AC coupled operation below 1kHz, add 0.1dB.
65. Exclusive of source input noise.
66. With AC coupling frequency = 3Hz and AC coupling filter = Slow.
67. For input impedance auto, bandwidth is 6kHz.
68. Specified with aperture auto and 4-wire short on input terminals. For 100V range, input
impedance 10MΩ, multiply by 2.5. For all ranges and sample rate >1k, add an additional 3×
RMS noise uncertainty to ppm of range.
69. Specified with aperture Auto, 100 Hz sine wave for sample rate ≤ 5 k, and 1 kHz sine wave for
sample rate ≥ 10 k. Distortion is calculated using first five harmonics.
