Amplitude range 0 to 90%. AM frequency: internal is 400Hz and 1kHz (±5%); external is DC to 20kHz (3 dB bandwidth)
Accuracy of ±5% of reading + 5% at a frequency of 1kHz. FM frequency: internal is ±5%: 400Hz and 1kHz; external is DC to 25kHz when frequency vernier is not in CAL position.
Peak deviation standard ranges are 0 to 10kHz and 0 to 100kHz. Accuracy of ±500 Hz on x1 range; ±5kHz on x10 range.
