調頻測量
調制頻率范圍: 25 Hz to 50 kHz
偏差范圍: 1,3,5,10, & 100 kHz
Measurements of positive and negative deviation and difference can be made.
精度度( 1 kHz modulation rate)：± (2％ of FS + 2％ of reading + residual FM).
調頻余量：＜ 20 Hz for carrier frequency up to 100 MHz. Above 100 MHz, increases linearly with frequency (20 Hz / 100 MHz).
De-Emphasis Selectable 50,75,750 μsec or off. Time constant accuracy = ± 5％.
調制頻率響應 referenced to 1 kHz
25 Hz –50 kHz FILTER ±5 dB in band
25 Hz – 15 kHz FILTER ±5 dB in band
300 Hz – 3 kHz –3dB ±5 dB at band limits.
調幅測量
調制頻率范圍：25 Hz to 50 kHz
調幅范圍: 10, 30, 50, and 100％
Measurements of peak, trough or difference can be made.
精確度（at 1 kHz modulation rate） ±(2％ of FS +2％of reading + residual AM ).
調幅余量：＜ 5％ with 15 kHz bandwidth.
信號輸出
中頻輸出 (Connector Rear-panel BNC)
頻率:～420 kHz
電平: 100 mV into 50 ohms
音頻輸出 (Connector Front-panel BNC)
電平: .5Vrms at 1 kHz modulation frequency eauals meter FS on any range .
頻率響應: Controlled by selected filter ( see AM and FM frequency response).
輸出阻抗: 600 ohms
失真度:
FM ＜ 1％ for 50 kHz deviation at 1 kHz modulating frequency.
AM ＜ 1％ for 80% AM at 1 kHz modulating frequency.
